Question

A 2-kg bowling ball sits on top of a building that is 40 meters tall.
Circle one: KE / GPE / both
Show your work for finding the values of each type of energy the object has.

2 Answer

  • The bowling ball is at rest, so it only has gravitational potential energy.

    Ug = mgy
    Ug = (2)(9.8)(40) = 784 J

  • A 2-kg bowling ball sits on top of a building that is 40 meters tall possess gravitational potential energy. It  is energy an object possesses because of its position in a gravitational field. We calculate as follows:

    GPE = mgh = 2(9.8)(40) = 784 J
