A spring with spring constant k is suspended from the ceiling. A block of mass M hangs from the spring. A bullet of mass m is fired vertically upward into the bottom of the block, get embedded in it, and the spring's maximum compression d is measured. The block and bullet system then oscillates. Find an expression for the bullet's speed vB in terms of m, M, k and d. Find the frequency ? of the oscillation. Find the...
