Question

A 12 kg block is at rest on an incline that is sloped at 37° above the horizontal.
One end of a light rope is attached to the block. The rope passes over a light frictionless pulley and the other end of the rope is attached to a hanging block of mass m. Nothing touches the hanging block except for the end of the rope. The coefficient of kinetic friction between the 12 kg block and the incline is 0.30. A force F = 36 N, directed down the incline parallel to the surface of the incline, is then applied to the 12 kg block and the block is observed to move 2.8 m down the incline in 3.0 s.

What is the acceleration of the 12.0 kg block? While the blocks are moving, what is the tension in the rope?
