A physics professor is pushed up a ramp inclined upward at an angle 28.0 above the horizontal as he sits in his desk chair that slides on frictionless rollers. The combined mass of the professor and chair is 85.0 . He is pushed a distance 2.25 along the incline by a group of students who together exert a constant horizontal force of 603 . The professor's speed at the bottom of the ramp is 2.15 .

Use the work-energy theorem to find his speed at the top of the ramp.

v = ? m/s
