Question

A smooth inclined plane is 6.00m long. The top end of the plane is 1.50m above the bottom end of the plane. A box which has a mass of 35.7kg is pulled up the plane by a rope which is parallel to the plane. The force in the rope is 99.6N. The initial speed of the box is 0. Calculate the speed of the of the box when the box is at the top of the plane.

99.6*6-35.7*9.8*1.50=1/2 *35.7*v^2
solve for velocity v at the top.
