Aperson is pushed up a ramp inclined upward at an angle θ above the horizontal as he sits in his desk chair that slides on frictionless rollers. the combined mass of the person and chair is m. he is pushed a distance x along the incline by a group of students who together exert a constant horizontal force of fa. the person’s speed at the bottom of the ramp is v0 m/s. use the work-energy theorem to find his speed at the top of the ramp.
