Two blocks with masses 0.90 kg and 3.90 kg are placed on a horizontal frictionless surface. A light spring is placed in a horizontal position between the blocks. The blocks are pushed together, compressing the spring, and then released from rest. After the blocks lose contact with the spring ends, the 3.90 kg mass has a speed of 1.00 m/s. The combined final kinetic energies of the blocks was originally stored in the spring. Determine how much potential energy was initially stored in the spring (in J)?

Two masses are connected on a frictionless pulley. M1 = 9 kg sits on a frictionless horizontal surface and is connected to a spring with a spring constant of k = 250 N/m. M2 = 6kg and hangs off the edge of the surface. Initially, both masses are at rest and the spring is at its equilibrium. After the blocks are released, how fast will they be moving when mass 2 falls .1 m?
