A 0.2 kg rubber ball is dropped from the window of a building. It strikes the sidewalk below at 30 m/s and rebounds at 20 m/s. The magnitude of the change in momentum of the ball as a result of the collision with the sidewalk is _______.

The mass of a dog is 35.8 kg. The dog runs into a bouncy wall at 10.0 m/s and bounces back in the opposite direction at 1.75 m/s. What is the magnitude of the dog's impulse n kgm/s?

A 51 kg boy on roller skates moves with a speed of 3 m/s. He runs into a 42 kg girl on skates. Assuming they cling together after the collision, what is their speed (in m/s)? (Assume the girl is initially at rest.) m/s

A 10.50-g bullet is fired into a stationary block of wood having mass m = 4.980 kg. The bullet imbeds into the block. The speed of the bullet-plus-wood combination immediately after the collision is 0.6090 m/s. What was the original speed of the bullet? (Express your answer with four significant figures.)  m/s

A 0.060 kg ball, initially moving at a speed of 10.0 m/s, is struck by a bat causing it to rebound in the opposite direction at a speed of 15.0 m/s. Calculate the magnitude of the impulse on the ball in the collision. Recall the impulse-momentum theorem.

A golf ball with a mass of 50 g is struck with a golf club. The force on the ball varies from zero when in contact to some maximum value (when the ball is maximally deformed) and then back tozero when the ball leaves the club. Assume that the ball leaves the club face with a velocity of 44 m/s. Find the magnitude of the impulse due to the collision

4. A 0.240 kg tennis ball is hit forward with a speed of 26.0 m/s. It is returned in the opposite direction at 37.5 m/s. What is the magnitude of the ball's change in momentum in this scenario?

A 9.7-g bullet is fired into a stationary block of wood having mass m = 5.10 kg. The bullet imbeds into the block. The speed of the bullet-plus-wood combination immediately after the collision is 0.606 m/s. What was the original speed of the bullet? (Express your answer with four significant figures.)

A 0.05 kg ball is thrown straight up into the air with an initial speed of 20 m/s. Find the momentum of the ball at the following locations. (a) at its maximum height kg-m/s (b) halfway to its maximum height kg-m/s

In a physics lab, a 0.500-kg cart moving at 36.4 cm/s collides inelastically with a second cart which is initially at rest. The two carts move together with a speed of 21.8 cm/s after the collision. Determine the mass of the second cart.
