Problem 1: A box is pulled up by a rope at a constant speed. If its mass 20 kg, its speed is 3 m/s, and the vertical distance of travel is 25 m, what is the work done by the rope on the box?

Problem 2: A box is pulled up by a rope at a constant acceleration. If its mass 30 kg, its upward acceleration is 1.5 m/s2, and the vertical distance of travel is 17 m, what is the work done by the rope on the box?
