two masses are connected by a massless string which runs across a massless, frictionless pulley. the heavier mass m2 is also connected to a spring, which is attached to the ground and has a spring Constant of K. Both masses are initially placed at the same height. When the masses are released, m2 begins to fall and compresses the spring. When the masses momentarily come to a stop, the spring has been compressed by a distance of d. Find an expression for the distance d that corresponds to the distance of maximum compression of the string. answer should only contain the parameters m1,m2,d, and the physical constant g.
