Chapter SH, Problem 4.12APP

To determine

To calculate: Gravitational potential energy.

Answer to Problem 4.12APP

Gravitational potential energy is $\underset{\_}{\text{2352 J}}$ .

Explanation of Solution

Given:

Mass = $\text{80 kg}$

Height = $3.0\text{ m}$

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:

  $\begin{array}{l}GPE=mgh\\ =(80\text{ kg)(9}\text{.8 N/kg)(3}\text{.0 m)}\\ =2352\text{ J}\end{array}$

Conclusion:

Gravitational potential energy is $\underset{\_}{\text{2352 J}}$ .
