consider a 2kg bowling ball sits on top of a building that is 40 meters tall. it falls to the ground. think about the amounts of potential and kinetic energy the bowling ball has​

Respuesta :

Answer:

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.
