a 250 g ball travels at a velocity of 40 m/s. its momentum is O 160 kg-m/s. O 10 kg-m/s. O 4 kg.m/s. O 10,000 kg·m/s
When a 250 g ball travels at a velocity of 40 m/s, its momentum is 10 kg-m/s.
In physics, momentum is defined as the product of an object's mass and velocity. It is a vector quantity, which means it has both magnitude and direction. The direction of momentum is the same as the direction of motion of the object.
The momentum of an object is equal to its mass multiplied by its velocity. Therefore, the momentum of a 250 g ball traveling at a velocity of 40 m/s is:
momentum = mass x velocity
momentum = 250 g x 40 m/s
momentum = 10,000 g-m/s
Note that the unit of momentum is usually represented as kgm/s, but since the mass is given in grams, we need to convert it to kg.

It is possible for the person to curl into a ball and start spinning after letting go of the rope. However, it would require some effort to initiate the spinning motion.
What do you mean by motion?An object changing its position with respect to time is referred to as motion. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, and speed.
As the person is falling, the only force acting on her body is gravity pulling her downward. Therefore, there is no horizontal force acting on her body to cause it to spin. However, if the person were to curl into a ball and then actively start spinning by twisting her body or flailing her arms, she could create a torque, which is a force that causes rotation.
It's worth noting that the spinning motion would not have a significant effect on the person's trajectory of falling into the swimming pool, as air resistance is negligible compared to her weight, and the spinning motion would be quickly dampened by the drag caused by the water resistance.

TRUE OR FALSE As a projectile rises towards the peak of its trajectory, the vertical acceleration is directed upward; as it falls from the peak of its trajectory, its vertical acceleration is directed downward. Group of answer choices
As a projectile rises towards the peak of its trajectory, the vertical acceleration is directed upward; as it falls from the peak of its trajectory, its vertical acceleration is directed downward. The correct answer is TRUE.
As a projectile is launched into the air, it initially experiences an upward acceleration due to the force applied to it. This acceleration causes the projectile to move upwards, until it reaches the peak of its trajectory. At the peak, the projectile's velocity in the vertical direction is zero and the acceleration is directed downward due to the force of gravity.
As the projectile falls back towards the ground, it experiences a downward acceleration, causing its velocity in the vertical direction to become negative. This acceleration continues until the projectile lands on the ground.

What is velocity vector?A velocity vector represents the rate of change of the position of an object. The magnitude of a velocity vector gives the speed of an object while the vector direction gives its direction. Velocity vectors can be added or subtracted according to the principles of vector addition.
Part A: To find the particle's speed at t = 0 s, we need to find the magnitude of its velocity vector. The velocity vector is given by the derivative of the position vector with respect to time. So: v = [tex]\sqrt{( (dx/dt)² + (dy/dt)² )}[/tex]
dx/dt = 36t² - 4t, dy/dt = 24t - 2
Therefore, at t = 0 s: v = [tex]\sqrt{(360^2 - 40)^2 + (24*0 - 2)^2 )}[/tex] = [tex]\sqrt{4}[/tex] = 2 m/s
Part B: To find the particle's speed at t = 5.0 s, we substitute t = 5.0 s into the equation for v: v = [tex]\sqrt{(365.0^2 - 45.0)^2 + (24*5.0 - 2)^2 ) }[/tex]= [tex]\sqrt{(1444)}[/tex] ≈ 38.2 m/s.
Part C: To find the direction of motion, we need to find the angle the velocity vector makes with the positive x-axis. We can use the arctangent function to find this angle: θ = atan(dy/dt / dx/dt)
Therefore, at t = 0 s: θ = atan( (240 - 2) / (360² - 4×0) ) = atan(-2/0) = undefined
Part D: To find the particle's direction of motion at t = 5.0 s, we substitute t = 5.0 s into the equation for θ: θ = atan( (245.0 - 2) / (365.0² - 4×5.0) ) ≈ 64.9 degrees

you encounter a 8.2 m long stretched string that is clamped at both ends. you launch a pulse from one end that returns in 0.57 s. what is the frequency of the 3rd normal mode in hz?
The frequency of the 3rd normal mode is 8.4 Hz.
What is frequency?The frequency of an event is the number of times it occurs each unit of time. It is often measured in hertz (Hz), which is the number of cycles per second.
The frequency of a normal mode in a stretched string is given by the equation:
f_n = (n*v)/2L, where f_n is the frequency of the nth normal mode, v is the wave velocity, L is the length of the string, and n is the mode number.
In this case, the length of the string is 8.2 m, the time it takes for the pulse to return is 0.57 s, the mode number is 3 and we are looking for the frequency of the 3rd normal mode.
We can first calculate the wave velocity, v, by dividing the length of the string by the time it takes for the pulse to return.
v = L/T
v = 8.2 / 0.57
v = 14.4 m/s
Now we can use this value of v to calculate the frequency of the 3rd normal mode:
f_n = (n*v)/2L
f_n = (314.4)/(28.2)
f_n = 8.4 Hz
So, the frequency of the 3rd normal mode is 8.4 Hz.

What explains the atomic theory?The atomic theory of matter aims to shed light on the composition of matter—the substances from which the universe, all galaxies, solar systems, and Earth are made. The atomic theory of matter asserts that every chemical element is composed of basic building blocks called atoms. John Dalston was the first to make this claim.
Atoms make up every form of matter. Atoms from the same element are identical, while atoms from other elements are distinct. Compounds are created when whole-number ratios of atoms combine.

What do you think are the factors that might affect the magnitude of this angle
The bond angle in a compound is the angle formed between two bonds in the compound. It is affected by the geometry, electron cloud and the size of atoms.
What is bond angle ?Bond angle is the distance between two chemical bonds in a compound. Bond angle is affected by the electrostatic force of repulsion and attraction. Hence, the presence of lone pairs and bond pair are the main factors affecting the bond angle.
If there are lone pairs, the repulsion between two lone pairs is greater than that between a lone pair and bond pair which in turn greater than that between two bond pairs.
Hence, the electron clouds will align themselves to minimize the repulsion. Thus, the geometry and bond angle may vary from what we predicted based on hybridization.

The speed of the players just after the successful tackle is 2.9 m/s.
In physics, what is a momentum?The amount of motion a body has is referred to as its momentum. Given that momentum depends on both velocity and the direction of the body's motion, it is quantified as "mass velocity". Because velocity is a vector, momentum is a vector quantity, whereas mass is a scalar quantity. Mass times speed equals momentum.
Ф = tan^-1 (m2 u2/m1u1) = 32.3
m1 u1 = (m1 + m2) v cosФ
v => m1u1/ (m1+m2) x cosФ
=> 90 x 5/(90+95) cos 32.3
=> 2.9 m/s.
What is the explanation for the law of conservation of momentum?The momentum conservation law says as much. Except for the application of an external force, the total momentum of two or more bodies operating on one another in an isolated system is constant. Determining momentum is impossible since it cannot be done.
