A 10 g bullet moving 1000 m/s strikes and passes through a 2.0-kg block initially at rest. The bullet emerges from the block with speed of 400 m/s. a.) How much energy was lost in the collision? b.) Calculate the average force exerted on the block assuming that the impact time is 10^-4 s. c.) To what maximum height will the block rise above its initial position?
