    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.
