a 5.00-kg bullet is fired with a velocity of 100.0 m/s toward a10.00 kg stationary solid block resting on a frictionless surface.
a) what is the change in momentum of the bullet if it is embeddedin the block?
b) what is the change in momentum of the bullet if it ricochets inthe opposite direction with a speed of 99 m/s?
c) in which case does the block end up with a greater speed?
