Jordan's car has more momentum because it weighs more.

Jordan's car accelerates faster due to its weight. Momentum is the result of a particle's mass and velocity. As a vector quantity, momentum has both magnitude and direction. Newton's second law, which may be expressed in its most general form as F = d p/dt, asserts that the force acting on a particle controls the rate of change of its momentum, p.

The second equation of motion of Isaac Newton states that the force applied to a particle is equal to the time rate of change of momentum. Since momentum depends on both the speed and the direction of the body's motion, it is expressed as "mass velocity." Since mass is a scalar and velocity is a vector, momentum is a vector quantity.

The electric motor takes 7,5 seconds to lift the 50 N. It is important to note that Power is a rate and energy is a scalar quantity.

To estimate the power required by a motor over a certain period of time, you would need to know the load that the motor will be driving (such as the weight of the object being moved, the resistance of the system, etc.) and the operating conditions (such as the speed at which the motor will be running, the duration of the operation, etc.).

Power = Force x velocity

From the text we know that the value of power is 1000 W. The value of force is 50 N and the distance is 150 m.

So, we get:

1000 = 50 N x velocity

Velocity = 20 m/s

To know how long a power rating of 1000 W can take the motor to lift a 50 N, we can use the formula:

s = v x t

Because we want to know the time, so the it will be

t = s/v

t = 150/20

t = 7,5 second

Or we can calculate it by this formula:

Power = work / time

Answer:

Explanation:

You want the speed of a 45.8 g golf ball after it has been hit by a 220 g club traveling 49.9 m/s, if the club is traveling 33.9 m/s in the same direction after the collision.

The conservation of momentum requires ...

  m1·v1 +m2·v2 = m1·v1f +m2·v2f

Rearranging this equation, we get ...

  m1·(v1 -v1f) = m2·(v2f -v2)

When v2 = 0, we can solve for v2f:

  m1(v1 -v1f)/m2 = v2f . . . . . . . divide by m2

In the given scenario, we have ...

The speed of the driven golf ball will be ...

  v2f = (220)(49.9 -33.9)/45.8 ≈ 76.9 . . . m/s

The speed of the golf ball after impact will be 76.9 m/s.

The correct answer is Option 3: her moment of inertia increases and her angular speed increases. When the lady extends her arms out, her moment of inertia increases because she is now further away from the axis of rotation and the mass of her arms is now contributing to her moment of inertia. Since her moment of inertia increases, her angular speed must also increase in order to conserve angular momentum.

The peak current through 200 ohm resistor for both the cases 50mA.

The number of turns times the size of the coil times the magnetic field's intensity times the angular speed equals peak emf.

The largest amount of current that an output is capable of providing for brief periods of time is known as the peak current. When an electrical device or power source is turned on for the first time, a large initial current known as the peak current flows into the load, starting at zero and increasing until it reaches a peak value.

A) To find the distance a sound wave travels in a certain time, we can use the formula:

distance = speed x time

Given that the speed of sound is 343 m/s and the time is 3000 microseconds, we can calculate the distance as:

distance = 343 m/s x (3000 x 10^-6 s) = 1.029 m

converting this to cm we get:

distance = 1.029 m x 100 cm/m = 102.9 cm

B) To find the time it takes for a sound wave to travel a certain distance, we can use the formula:

time = distance/speed

Given that the distance is 30 cm and the speed of sound is 343 m/s, we can calculate the time as:

time = 30 cm / 343 m/s = 0.00087 s

converting this to microseconds we get:

time = 0.00087 s * 10^6 microseconds/s = 87 microseconds

C) The time it takes for the sound wave to travel to the object and back is twice the time it takes for the sound wave to travel to the object alone. Given that the distance is 50 cm and the speed of sound is 343 m/s, we can calculate the time as:

time = 2 * (50 cm / 343 m/s) = 2 * 0.000146 s = 0.000292 s

converting this to microseconds we get:

time = 0.000292 s * 10^6 microseconds/s = 292 microseconds

So it takes 292 microseconds for a sound wave generated to bounce and gets back from an object 50 cm away.

A temperature of 100 degrees Fahrenheit is equivalent to 37.78 degrees Celsius.

The conversion formula between Fahrenheit and Celsius is as follows:

°C = (100 - 32) x (5÷9) = 68 x (5÷9) = 37.78

It is important to note that the degree unit size (Fahrenheit and Celsius) is not the same, and thus the numerical value of the temperature measured in those scales does not match one to one. The freezing point of water is 32 degrees Fahrenheit (0 degrees Celsius) and the boiling point is 212 degrees Fahrenheit (100 degrees Celsius).

Car A and car B of equal mass travel up a hill. Car A moves up the hill at a constant speed that is twice the constant speed of car B. Compared to the power developed by car B, the power developed by car A is four times as great.

The power developed by a vehicle is the product of its mass and acceleration. Car A has the same mass as car B but is traveling at twice the speed. Therefore, if the speed of Car A is double the speed of Car B, then the acceleration of Car A must be double that of Car B. This means that the power developed by Car A must be four times the power developed by Car B.

This is because the power is equal to the mass multiplied by the acceleration, so if the acceleration is double, then the power must also be double. The power of a vehicle also depends on the amount of friction, or resistance, it encounters. Since Car A and Car B have the same mass, any difference in the power developed by each car is solely due to the difference in their speeds.

The disk will rotate through an additional angle of 52.5 rad during the next 7 seconds.

Angular acceleration is scaled in units of angle per unit time   squared (which in SI units is radians per second squared) and is ordinarily characterized by the symbol alpha( α). It is a pseudovector quantity.

To find the additional angle the disk will turn during the next 7 seconds, we can use the equation for angular displacement: Δθ = α × t² / 2 + ωi × t Where: α = angular acceleration (constant), t = time ,ωi = initial angular velocity (which is 0, since the disk is starting from rest)

We know the angular acceleration and time, so we can plug in the values to get: Δθ = α × (7.0s) ² / 2 + 0 × 7.0s

We don't know the angular acceleration, but we know the final angular displacement, which is 30 rad and the time taken which is 4s, so we can use the equation Δθ = α × t²/2 + ωit 30 = α × 4² / 2 + 04

Solving for α, we get: α = 30/8 rad/s²

Now we can use this value of angular acceleration to find the additional angle the disk will turn during the next 7 seconds: Δθ = α × (7.0s) ² / 2 + 0 × 7.0s

Δθ = (30/8) × (7.0s) ² / 2 + 0 × 7.0s

Δθ = (30/8) × 49/2

Δθ = 52.5 rad

Answer:

To find the number of antinodes in the standing wave pattern, we need to find the wavelength of the fifth harmonic. The fifth harmonic has a frequency of 5 times the fundamental frequency, and the fundamental frequency is equal to the speed of sound divided by the length of the pipe. Thus, the wavelength of the fifth harmonic is the speed of sound divided by 5 times the fundamental frequency, which is equal to 340 m/s / (5 * (340 m/s / 1.5 m)) = 0.3 m.

Since the length of the pipe is 1.5 m, and the wavelength is 0.3 m, there will be 1.5 m / 0.3 m = 5 full wavelengths in the pipe. Since there is an antinode at both ends of the pipe, there will be a total of 5 + 2 = 7 antinodes in the standing wave pattern. Therefore, the correct answer is (C) 7.

The acceleration of the boxes are 1.625 m/s^2.

What is acceleration?

Acceleration is a measure of how much an object's velocity changes over time. Velocity is a vector quantity that includes both speed and direction, so acceleration can refer to changes in speed, direction, or both. Acceleration is typically measured in meters per second squared (m/s^2) or feet per second squared (ft/s^2). Positive acceleration indicates an increase in speed, while negative acceleration indicates a decrease in speed.

To find the acceleration of the boxes, we can use the formula:

force = mass x acceleration.

In this case, we know the force applied (39.0 N) and the mass of the boxes (9.00 kg + 14.0 kg + 1.00 kg = 24.00 kg).

So we can calculate the acceleration as:

force = mass x acceleration

39.0 N = 24.00 kg x acceleration

acceleration = force / mass

acceleration = 39.0 N / 24.00 kg

acceleration = 1.625 m/s^2

it will take the cheetah 1.118 seconds to move at 25.0 mph.

Kinematic equations are mathematical equations used in physics to describe the motion of objects. These equations are used to solve problems involving velocity, acceleration, and displacement. The equations rely on the use of Newton's laws of motion, which state that the acceleration of an object is equal to the sum of all the forces acting upon it, divided by its mass.

First let's convert 25.0 mph to m/s:
25 mph = 11.176 m/s
Now we can use the kinematic equation for uniform acceleration:
vf = vi + at
where vf is the final velocity, vi is the initial velocity (which is 0 m/s since the cheetah is starting from rest), a is acceleration (10.0 m/s2), and t is the time interval.

Explanation:

Work Done = Force X Distance moved in a stated direction

Work Done = 3N + 5N X 6m

Work Done = 48 J

Two forces 3N and 5N acting on an object are inclined at 60 degrees to each other. If the resultant force moves the object a distance of 6m, the work done is 35.92 Joules (J).

In physics, work is defined as the transfer of energy that occurs when a force is applied to an object and the object is displaced in the direction of the force. Mathematically, work done is the product of the force applied and the distance moved in the direction of the force.

Work is a scalar quantity and is measured in joules (J) in the International System of Units (SI). When a force is applied to an object and there is no displacement, no work is done. Similarly, if there is displacement but no force acting on the object, no work is done.

Here in the Question,

To find the work done, we need to first find the resultant force.

Using vector addition, we can find the magnitude and direction of the resultant force:

cos(60) = adjacent/hypotenuse

adjacent = cos(60) x 5N = 2.5N

sin(60) = opposite/hypotenuse

opposite = sin(60) x 5N = 4.33N

The horizontal component of the 3N force is 3N cos(60) = 1.5N

The vertical component of the 3N force is 3N sin(60) = 2.6N

The horizontal component of the 5N force is 5N cos(30) = 4.33N

The vertical component of the 5N force is 5N sin(30) = 2.5N

The horizontal component of the resultant force is 4.33N + 1.5N = 5.83N

The vertical component of the resultant force is 2.5N + 2.6N = 5.1N

The magnitude of the resultant force is given by the Pythagorean theorem:

Resultant force = sqrt(5.83^2 + 5.1^2) = 7.59N

The direction of the resultant force is given by:

tan(theta) = opposite/adjacent

theta = tan^-1(5.1/5.83) = 43.1 degrees

The work done is given by:

work = force x distance x cos(theta)

work = 7.59N x 6m x cos(43.1) = 35.92 Joules (J)

Therefore, the work done is 35.92 Joules (J).

if it didn't have a ramp it would be harder to load the truck.

Ladybug covers distance from the moment she begins to decelerate until she comes to the rest. The deceleration is 0.25m/ s2.

The net work done on a body is equal to change in kinetic energy of the body. This is called as Work-energy theorem.

Numerically. To find the distance, which Ladybug cover from the moment she begins to decelerate until she comes to the rest, use the formula.

Where,  is final velocity,  is initial velocity,  is acceleration and  is displacement. After moving, ladybug comes to the rest, so final velocity,  Placing the value of the given initial velocity, , acceleration.

Therefore, Ladybug covers  distance from the moment she begins to decelerate until she comes to the rest.
