**drwls**, Saturday, November 7, 2009 at 3:17pmFor each of your questions, the gravitational P.E. is M g times the distance of the ball above the reference plane. "g" is the acceleration of gravity.

That distance is zero for part (c).

Now you calculate the others. One answer will be negative, if done correctly.

The answers should be in Joules.
