1. A vertical spring has a spring constant of 2500 N/m. A ball with a mass of 0.25 kg is on top of the spring. Use energy conservation to answer the following questions. Sketch the situation for each part.

A. If the spring is compressed 8.3 cm how much energy is stored in the spring?

B. When you release the spring, it pushes the ball upward. What is the speed of the ball at the instant it leaves the spring? The spring is at its relaxed length at this point.

C. How far above the spring will the ball rise before it stops going up?
