A snowball at the top of a small mountain breaks in half. One half rolls down the left side and the other down the right side, as shown below. Given that the mountain is 45m tall, determine the change in potential energy of each snowball.
A ball moves horizontally on a spring. The spring is originally stretched 0.2m. Some time later, the spring is compressed 0.1m. What is the total change in potential energy (in terms of k)?

Unformatted text preview: spring changes from 0.5m to 1.0m? A ball moves on a spring at a 30° angle below the horizontal. The equilibrium length of the spring is 1.5m. What is the change in potential energy of the earth-ball-spring system as the total length of the spring changes from 0.5m to 1.0m. The potential energy vs. position of a particular system is shown in the graph below. Rate the magnitude of the force from least to greatest. Also, which point has the greatest force in the positive x direction? U(J) A B C D x (m)...
