A physics professor is pushed up a ramp inclined upward at 30.0degrees above the horizontal as he sits in his desk chair thatslides on frictionless rollers. The combined mass of the professorand chair is 85.0kg. He is pushed 2.50m along the incline by agroup of students who together exert a constant horizontal force of600N. The professor's speed at the bottom of the ramp is 2.00m/s.Use the work-energy theorem to find his speed at the top of theramp.
