    •

    Q:

    		 A mass lies on a horizontal, frictionless beam and is attached to a horizontal spring with spring constant k. At full extension, the potential energy of the system is U while the kinetic energy, K, of the system is 0. What is the ratio of the potential energy to kinetic energy when the spring is at half its full extension, assuming the mass is released from full extension?
