Question

A small object is held down on a spring as shown below (left side of the picture). The object is then released and it flies upward (sort of like a jack-in-the-box). It reaches a maximum height of h as shown (right side of picture). The equilibrium length of the spring is L0. Match the items listed below with one of the graphs shown. Note that in each graph, some quantity is plotted versus the object's vertical position (i.e., position in y). If no plot matches, write N for none.

1.) The spring potential energy

2.) The kinetic energy of the object

Explanation / Answer

1. answer is............. c

2. answer is ...................e at maximum height kinetic energy is zero and at mean position it is maximum
