A 20.0-kg box is at rest at the bottom of a 20.0 m -long ramp that makes an angle 30° with the horizontal. A constant horizontal force of 290 N is applied to the box to push it up the ramp. While the box is moving, the ramp exerts a constant frictional force on it that has magnitude 65.0 N.

a. Calculate the total work done on the box during its motion from the bottom to the top of the ramp?

b. How long does it take the box to travel to the top of the ramp?
