A spring with spring constant k is attached to the floor, standing vertically. You place a box of mass m on the spring and, from rest, release it. The spring bounces up and down a few times and comes to rest (both its velocity and acceleration are zero). Find the thermal energy generated in this process in terms of m, g, and k. Answer Options: A. mg/k   B. m^2 g/k C. m^2 g^2/k   D. m^2 g^2/ 2k   E. mg/2k
