A massless pan hangs from a spring that is suspended from the ceiling. When empty, the pan is 50cm below the ceiling. If a 100g clay ball is placed gently on the pan, the pan hangs 60cm below the ceiling. Suppose the clay ball is dropped from the ceiling onto an empty pan.
What is the pan's distance from the ceiling when the spring reaches its maximum length?
