A 10 g bullet moving 1000 m/s strikes and passes through a 2.0-kg block initially at rest, as shown. The bullet emerges from the block with a 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 10-4s. (c) to what maximum height will the block rise above its initial position?
