Question:

A massless pan hangs from a spring that is suspended from the ceiling. When empty, the pan is 47 cm below the ceiling. If a 100 g clay ball is placed gently on the pan, the pan hangs 75 cm below the ceiling. Suppose the clay ball is dropped from the ceiling onto the empty pan. What is the pan's distance from the ceiling when the spring reaches its maximum length?

Kinematics of Spring:

An elastic spring follows Hook's law and it states that in an elastic body force applied to stretch the body is directly proportional to stretched length. When a spring is compressed or stretched, the work done in stretching or compressing is stored as potential energy of spring.
