The system below consist of identical massed (m1, and m2) that are connected by a string of negligible mass. Mass m1, is on a frictionless horizontal surface. The string runs over a frictionless pully (also of negligible mass) to mass m2. Mass m2, is initially held in place with a force F. While F is applied to m2, the system is at rest. At t=0, m2, is released.
The initial distance from m, to the pulley is the same as the initial distance from m2 to the wall. Will m1, collide with the pulley before or after m2 collides with the wall? Provide a conceptual explanation (not a calculation) is support of your answer. You might want to begin by drawing a free diagram after m2 is released.
