Chapter SH, Problem 4.16APP

To determine

To calculate: Gravitational potential energy.

Answer to Problem 4.16APP

Gravitational potential energy is $\underset{\_}{\text{10000 J}}$ .

Explanation of Solution

Given:

Weight = $500\text{ N}$

Height = $\text{20 m}$

Formula used:

Gravitational potential energy is given by,

  $GPE=mgh$

where $m$ is mass, $g$ ( $\text{9}\text{.8 N/kg}$ ) is gravity and $h$ is height.

Calculation:

Gravitational potential energy is calculated as:

  $\begin{array}{l}GPE=mgh\\ =(500\text{ N)(20 m)}\\ =10000\text{ J}\end{array}$

Conclusion:

Gravitational potential energy is $\underset{\_}{\text{10000 J}}$ .
