Question

A ball with a mass 0.085 kg is held 1.62 m above the ground. What is the gravitational potential energy of the ball in Joules? (2 decimal places)

Answer 1

ANSWER

$1.35J$

EXPLANATION

The gravitational potential energy of the ball can be calculated by using the formula:

$PE=mgh$

where m = mass of the ball

g = acceleration due to gravity = 9.8 m/s²

h = height of the ball above the ground

Therefore, the gravitational potential energy of the ball (in 2 decimal places) is:

$\begin{gathered} PE=0.085\cdot9.8\cdot1.62 \\ PE=1.35J \end{gathered}$
