Momentum Conservation: Inelastic Collision

A 5.00-g bullet is fired with a velocity of 100 m/s toward a 10.0-kg stationary solid block resting on a frictionless surface.

a.  What is the change in momentum of the bullet if it is embedded in the block?

b.  What is the change in momentum of the bullet if it ricochets in the opposite direction with a speed of 99 

      m/s- almost the same speed as it had originally?

A 50-kg girl throws a 5.0-kg pumpkin of 10 m/s to a 50-kg boy, who catches it.  If both are on a frictionless frozen lake, how fast does each of them move backward?
