1. The problem statement, all variables and given/known data Two identical blocks are attached by a massless string running over a pulley. The rope initially runs over the pulley at the rope's midpoint, and the surface that block 1 rests on is frictionless. Blocks 1 and 2 are initially at rest when block 2 is released with the string taut and horizontal. Will block 1 hit the pulley before or after block 2 hits the wall? (Assume that the initial distance from block 1 to the pulley is the same as the initial distance from block 2 to the wall.) See Attached Figure 2. Relevant equations Fnet = ma Fg = mg Fc = mv^2/r 3. The attempt at a solution I know that block 1 hits the pulley first. But Korunsky says that the solution is very simple. I am not sure if I am right. I can draw a freebody diagram showing that tension acts on block 1 and is equal to the net force. I can also draw a freebody diagram showing that Tension - mgcosΘ is equal to the net force. Would this mean that the acceleration of the second block is less than the acceleration of the first block? Is this why block 1 hits the pulley first?
