a sled of length 10L, mass 2M, and uniform mass density rests on level, snow covered ground (the surface is frictionless). A spring of force constant k is compressed a distance l from equilibrium so that when the mass M is placed in front of it, it is a distance 2L from the right end of the sled. The mass is released from rest and slides without friction across the sled and off the left end. The mass of the spring is negligible. Consider the moment when the mass is just about to leave  the end of the sled. a, How far has the sled moved from its initial position and in what direction? b. what is the speed of sled ?
