A physics professor is pushed up a ramp inclined upward at an angle 29.0∘ above the horizontal as he sits in his desk chair that slides on frictionless rollers. The combined mass of the professor and chair is 80.0 kg. He is pushed a distance 2.40 m along the incline by a group of students who together exert a constant horizontal force of 610 N. The professor's speed at the bottom of the ramp is 2.15 m/s. Part A Use the work-energy theorem to find his speed at the top of the ramp. Express your answer in meters per second. v = m/s
