Madden Fritz · Answer 1

Kinetic energy is 0 J. Potential is 784 J.

Explanation:

Recall that KE = 1/2 (m) (v²) and PE = mgh.

The kinetic energy is 0 because the velocity is 0. The potential energy is PE = (2) (9.8) (40), assuming the ball is on earth. Use the equations to plug in the information you know.
