EX1: A crate of mass m 1 rests on a frictionless horizontal surface. The crate is connected to a box of mass m 2 that hangs off the surface by a massless rope that lies across a massless, frictionless pulley. Find the acceleration of the crate, the normal exerted by the surface on the crate, and the tension in the rope.
