A 6 Kg block is on a frictionless plane inclined at 37 degrees. The block is attached by a weightless cord passing over a frictionless peg to a hanging block of mass 4 Kg.
a) Find the acceleration of the blocks.
b) Find the tension in the cord.
c) How long does it take the 6 Kg block to move 2m along the plane, starting from rest?
d) Does it go up the plane or down? How do you know?
