A 0.012-kg bullet, traveling at 850 m/s, hits a 2-kg block of wood that is initially at rest, and goes straight through it. Assume that the final velocity of the bullet relative to the block is 400 m/s, and that the system is isolated.

(a) What is the coefficient of restitution for this collision?

(b) How much kinetic energy is “lost” in the collision?

(c) What is the final velocity of the block?
