8. A .5 kg soccer ball is kicked with a force of 50 N for .25 s. What is the change in momentum caused by the kick

Answers

Answer 1

The mass of soccer ball is 5 kg. A ball got a force (50 N) which caused change in momentum for 25 second.

The value of the change in momentum can be described below :

The change in momentum is called as Impuls.

The formula of Impuls --> I = F × t

I = Impuls, F = Force (N), t = time (s)

I = F × t

I = 50 × 25 = 1250 Ns

So, the change in momentum of 5 kg ball is 1250 Ns.

Below are sample standard word problems involving application of Newton's laws of motion.
1. A box with mass 10.5 kg moves on a ramp that is inclined at an angle of 50.0∘ above the horizontal. The coefficient of kinetic friction between the box and the ramp surface is μk = 0.310. Calculate the magnitude of the acceleration of the box if you push on the box with a constant force F = 125.0 N that is parallel to the ramp surface and directed up the ramp, moving the box up the ramp.
2. A 60.0-kg crate rests on a level floor at a shipping dock. The coefficients of static and kinetic friction are 0.760 and 0.410, respectively. What horizontal pushing force is required to just start the crate moving and slide the crate across the dock at a constant speed? Note: Two FBDs will be provided here. The first FBD is for the crate that is about to move and the second FBD is for the crate that is already in motion at a constant speed.
Disregard the calculation part, your task is to (a) identify the forces acted on the object (in bold) and (b) draw its FBD. For Part A, you will be graded based on the correctly identified force. For each wrongly identified force, it will be deducted from your correct ones. For Part B, you will be graded based on the accuracy and completeness of your FBD with 5 points as the maximum score and 0 point as the lowest score.

Answers

The magnitude of the acceleration of the box if you push on the box with a constant force F = 125.0 N that is parallel to the ramp surface and directed up the ramp is 9.96 m / s²

N = m g cos θ

N = 10.5 * 9.8 * cos 50°

N = 65.86 N

∑ [tex]F_{x}[/tex] = m a

F - f = m a

F - μ N = m a

125 - ( 0.31 * 65.86 ) = 10.5 * a

125 - 20.42 = 10.5 a

a = 104.58 / 10.5

a = 9.96 m / s²

To just start the crate to move,

Fs = μs m g

Fs = 0.76 * 60 * 9.8

Fs = 446.88 N

To slide the crate across the dock at a constant speed,

F = μk m g

F = 0.41 * 60 * 9.8

F = 241.1 N

Therefore,

1 ) a = 9.96 m / s²

Answers

Net force at highest position is force due to gravity= m*g

net acceleration of ball at highest point is = g towards ground

What is force?

Force can be understood as the push or pull on an object with mass that  causes it to change its velocity. Force is external and is capable of changing a body's state of rest or motion.

When a person kicks the ball with initial force Fo,  then energy associated with this force is transferred to the ball in the form of momentum change and hence velocity of ball is non zero.

In this case impulse imparted by the force is equal to change in momentum of the ball.

The only force acting on the ball at his highest is is the force due to gravity.

What force has to be overcome in order for your balloon car to start to move? Once it is moving and all the air is expelled why does your car keep moving? What causes it to stop?

Answers

It has to overcome friction and air resistance in order for your balloon car to start to move

What is a balloon car?

For balloon-powered car, the contracting balloon pushes the air in the balloon backwards. That means the air in the balloon is pushing balloon forwards. The balloon is joined to car, so the car rolls. The motion is nothing to do with pushing on the air behind car.

There are two main forces acting on balloon rocket car: Friction and Air resistance. The friction force is resistance between two objects sliding against each other. While building your car identify places where objects will be rubbing against each other creating friction. In order to get car to move, we need an unbalanced force. In other words, the force of air coming out of balloon must overcome the forces acting on the car. We will want to reduce friction and air resistance to help your car move.In the case of balloon car, the action is the air rushing out of the balloon, pushing against air behind the car. The opposite or equal reaction is that the air behind car pushing against the car with the same force, causing the car to propel forwards.The weight of car is too great and nothing moves: As the car weight increases, friction between axle and straw, wheel and axle, and wheel and floor increase. There comes a point where the forces from friction are greater than the force from air blowing out the balloon.

Suppose you have a barometer with mercury and a barometer with water. How does the height hwater compare with the height hmercury?.

Answers

The heaviest liquid is mercury. In order to equalize the air pressure, it only climbs 76 cm. Water will rise to a 13.6 because it is 13.6 times lighter than mercury. By a factor of 13.6, mercury is 13.6 times denser than water.

Therefore, the barometer's height would be 13.6 times higher if water were employed in place of mercury. Since water expands when it freezes, the glass tube would be broken.

Because of its high density, mercury is frequently employed in barometers, allowing for a column height that is appropriate for measuring atmospheric pressure. For example, a mercury barometer would need to be 13.6 times taller than a water barometer to measure the same change in pressure.

This is the primary justification for using mercury in thermometers. Mercury will provide accurate readings in comparison to water since it lacks the condensation property that water possesses.

Explanation:

Which of the following is not true for a load-extension graph up to the limit of proportionality?

a) It is a straight line   (TRUE)

(See graph)

b) It can cross the y-axis at any point (FALSE)

c) Extension ÷ load always equals the same value   (TRUE)

 ΔL / P = 1/k  (k - stiffness)

d) If the load is doubled, then the extension is doubled  

P = k·ΔL

2·P = k·(2·ΔL)

A 30.0 kg object is falling in air and experiences a force due to air resistance of 50.0 N. What is the net force acting on the object?

A) -244 N
B) -110 N
C) 94 N

Answers

The net force acting on the object will be 244 in downward direction

Forces acting on a freely falling body will be

1) Force due to gravity ( in downward direction ) or gravitational force

2) Force due to air resistance ( in upward direction )

Net force =  Force due to gravity  - Force due to air resistance

                = - mg + Force due to air resistance

                = - 30 * 9.8 + 50

                = - 294 + 50 = -244 N

correct answer is

A) -244 N

Answer:

A.Running 50 m along a straight track

Explanation: Running 50 m along a straight track is a real-world example of linear motion.Linear motion means moving along a (straight) line, a direct and straight line from point A to point B.All the other proposed answers (A,B,C) involve a curve.  The two rock examples will curve due to gravity and running around a curve on a track isn't a straight line.I hope that helps you understanding the principle of linear motion.

Answer:

A. Running 50m along a straight track

Explanation:

Linear motion is the motion that is natural to an object: moving in a straight line. An object not affected by any force will continue indefinitely in a straight line.

if the mass and the momentum of an object are given

Answers

The formula for linear momentum is p = mv. The relationship between momentum and an object's mass and speed is straightforward. Therefore, an object's momentum increases with increasing mass or velocity. The vector of momentum p has the same direction as the vector of velocity v.

Linear Momentum:

The product of an object's mass, m, and its velocity, v, is the vector quantity known as linear momentum. It is represented by the letter "p," which is also used to denote momentum. Please be aware that the body's momentum always points in the same direction as its vector of velocity. Because it is a conserved quantity, a system's overall momentum is always constant. kg/s is the unit of linear momentum.

A golf ball leaves the club with a horizontal velocity of 10 m/s and a
vertical velocity of 15 m/s. Calculate the resultant velocity of the golf ball.

Answers

The resultant velocity of the golf ball is 18.03 m/s

What is Resultant velocity?

An object's total vector velocity is the sum of its component vector velocities. The scalar product of an object's mass and acceleration vector equals the sum of the vector forces acting on it. If indeed the two objects stick together again after impact, divide the total momentum even by sum of the masses. You will then be given the two objects' resultant velocity as a result. In the aforementioned example, 50 would be divided by the total mass of the masses, which really is 10, yielding a speed of 5 metres per second.

Horizontal velocity= 10 m/s

Vertical velocity= 15 m/s

Resultant velocity= [tex]\sqrt{100+225}[/tex] = [tex]\sqrt{325}[/tex] = 18.03 m/s
