A massless pan hangs from a spring that is suspended from the ceiling. When empty, the pan is 49 cm below the ceiling. If a 75 g clay ball is placed gently on the pan, the pan hangs 60 cm 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?

first i did k = .735/.11 = 66.8181

then i used k = mgh/d to find the max length

which was 66.8181 = 3.6015/d and got d = 5.39 but that wasn't the correct answer. can somebody help me with what i am doing wrong?
