A block, mass = m1, lies on an incline of angle theta, and is connected to a second block of mass m2=3/2 m by a string that passes over a light frictionless pulley. The second block hangs vertically and is firmly attached to a spring that has negligible mass and a force constant of k. The opposite end of the spring is firmly attached to a horizontal surface. The spring is unstretched, when both masses are in their equilibrium positions. The surface of the incline is frictionless. The block atop the spring is a distance h above the horizontal surface when the spring is unstressed.
Now the mass m1 is pulled down the incline a distance h from the equilibrium position and released. What is the speed of both blocks when they pass through their equilibrium points?
