1
Lee has a mass of kg and ice skates with a speed of m/s. She collides into Mat ( kg) who is standing still on the ice. They move off together. What is their final speed in m/s?

2
A -kg gun at rest contains a -kg bullet. When fired, the bullet leaves the gun with a forward velocity of m/s. What is the recoil velocity of the gun in m/s?

3
A g ball moving to the right at m/s is struck by a bat causing it to move to the left with a speed of [y] m/s. If the bat and ball are in contact for s, what is the average force in N exerted by the ball on the bat?

4
A -kg boy running at m/s jumps onto a stationary cart. They move off together at m/s. What is the mass of the cart in kg?

5
A kg football player running m/s in the positive direction tackles a kg opponent running toward him at 10.0 m/s and holds on. What is their velocity in m/s just after the collision?
