Suppose you do 2 J of work on a guitar string by stretching the middle to some maximum position. Then you let go.

How much potential energy and kinetic energy does the string have right after you let go, when it passes through its equilibrium, and when it reaches the maximum in the other direction.

12. a. You do 31 J of work to move a -15 uC from infinity to a spot some distance away from a -11 uC charge. What is that distance? [4.8 cm] b. The work you did is stored as potential energy in the system as long as the charges are both held fixed in that position. You then let the -15 uC charge go. If that point charge has a mass of 7.2x10-12 kg, how fast will it be...

A ball with a mass of 270 g is tied to a light string that has a length of 2.40 m. The end of the string is tied to a hook, and the ball hangs motionless below the hook. Keeping the string taut, you move the ball back and up until it is a vertical distance of 1.16 m above its equilibrium point. You then release the ball from rest, and it oscillates back and forth, pendulum style. As usual,...
