A 110 N force pulls a 5 kg cube up an incline. The incline is 9 meters long and makes a 220 angle with horizontal. The cube is moving initially with a velocity of 1 m/s and the kinetic friction coefficient between the cube and the incline is 0.28. Calculate work done by each force acting on the cube. Find the velocity of the cube at the end of 9 meter incline.
