Question

A(n) 15.9 kg rock is on the edge of a(n

Answer 1

The potential energy (P.E) of the rock relative to the base of the cliff is 31,054.926 Joules..

Given the following data:

• Mass of rock = 7.5 kg

• Height = 0.7 m

• Acceleration due to gravity = 9.8 $m/s^2$

To calculate the potential energy (P.E) of the rock relative to the base of the cliff:

What is potential energy?

Potential energy (P.E) can be defined as the energy that is possessed by an object due to its position (height) above planet Earth.

Mathematically, potential energy (P.E) is given by this formula;

$P.E = mgh$

Where:

• P.E is the potential energy.

• m is the mass of an object.

• g is the acceleration due to gravity.

• h is the height of an object.

Substituting the given parameters into the formula, we have;

$P.E = 15.9 \times 9.8 \times 199.3$

P.E = 31,054.926 Joules.
