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

The height of the cliff in meters = 27.44

Step-by-step 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
