Is this elastic or inelastic? Sam and Talia run towards each other, hit against each other, and BOUNCE off each other in opposite directions.

What is the unit for momentum?

When you jump you usually bend your knees upon reaching the ground. By doing this, you make the time of the impact about 10 times as great as for a stiff-legged landing. In this way the average force your body experiences would be...

The force on an apple hitting the ground depends upon A) the speed of the apple just before it hits. B) the time of impact with the ground. C) whether or not the apple bounces. D) all of these

Compared to the force that brings a small car to a stop, the force required to bring a heavy truck to a stop A) is less. B) is more. C) is the same. D) impossible to determine without additional information

A bullet is fired from a gun. The speed of the bullet will be about the same as the speed of the recoiling gun if the mass of the bullet...

A 1-kg chunk of putty moving at 1 m/s collides with and sticks to a 5-kg bowling ball initially at rest. The bowling ball and putty then move with a total momentum of...

It is correct to say that impulse is equal to A) momentum. B) the change in momentum it produces. C) the force multiplied by the distance the force acts. D) velocity multiplied by time.

A 5-kg fish swimming at a speed of 1 m/s swallows an absent-minded 1-kg fish at rest. The speed of the larger fish after this lunch is...
