Two different masses are sitting on a frictionless track with a compressed spring between them which has 4.0 J of potential energy. When released, the spring pushes the masses apart. If one mass is 2.0 kg and the other mass is 5.0 kg, what is the speed of each mass after the spring stops pushing them apart? Assume the mass of the spring is negligible.

A 200-g steel ball is tied to a 2.00m “massless” string and hung from the ceiling to make a pendulum, and then, the ball is brought to a position making a 30 angle with the vertical direction and released from rest.

Repeat the preceding problem, but this time, suppose that the work done by air resistance cannot be ignored. Let the work done by the air resistance when the skier goes from A to B along the given hilly path be —2000 J. The work done by air resistance is negative since the air resistance acts in the opposite direction to the displacement. Supposing the mass of the skier is 50 kg, what is the speed of the skier at point B ?
