A 22-g bullet traveling 210 m/s penetrates a still 2-kg block that is 1 m thick and emerges going at 150 m/s. Assume the block stays still until the bullet exits it. (a) What is the bullet's momentum before striking the block? (b) What is the speed of the block after the bullet goes through it? (c) How much mechanical energy was lost in the collision? (d) What is the impulse applied to the bullet? (e) How long does it take for the bullet to travel through the block?
