Question

A 13 kg rock is sitting on a cliff. If the rock has 3,500 joules of potential energy, what is the height of the cliff in meters?(Round the answer to the nearest tenth. Show work

Answer 1

Answer:

The height of the cliff in meters = 27.44

Explanation:

 The potential energy of a body is given by the expression, PE = mgh, where m is the mass of the body, g is the acceleration due to gravity value and h is the height of the body.

 Here we have mass of rock = 13 kg

                          Potential energy = 3500 J

                          Acceleration due to gravity  = $9.81m/s^2$

                          Substituting   3500 = 13 * 9.81 * h

                                                       h = 27.44 meter

      The height of the cliff in meters = 27.44
