A sled with mass 12.00 kg moves in a straight line on a frictionless horizontal surface. At one point in its path, its speed is 3.00 m/s; after it has traveled a distance 4.00 m beyond this point, its speed is 5.00 m/s. Part A Use the work-energy theorem to find the force acting on the sled, assuming that this force is constant and that it acts in the direction of the sled's motion. Express your answer with the appropriate units.

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
