Explain the work-energy theorem

Reference no: EM13241946

A physics professor is pushed up a ramp inclined upward at an angle 34.0 degrees above the horizontal as he sits in his desk chair that slides on frictionless rollers. The combined mass of the professor and chair is 89.0 kg. He is pushed a distance 2.45 m along the incline by a group of students who together excert a constant horizontal force of 606 N. The professor's speed at the bottom of the ramp is 1.70 m/s.

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