A physics professor is pushed up a ramp inclined upward at an angle25.0 above the horizontal as he sits in his desk chair that slideson frictionless rollers. The combined mass of the professor andchair is 83.0 . He is pushed a distance 2.45 along the incline by agroup of students who together exert a constant horizontal force of602 . The professor's speed at the bottom of the ramp is 1.85.
A)Use the work-energy theorem to find his speed at the top of theramp?
