A block of mass `180 g` is placed on a spring (spring constant `k = 120 N//m`) fixed from below. A ball of mass `20 g` is dropped from height `20 m` and the collision is completely inelastic. Find the maximum compression of the spring. Neglect the initial compression of the spring due to the block.
