Question

Questions to consider:

Answer 1

Answer: 2352 J

Explanation:

A body's gravitational potential energy $U$ depends on its position and is mathematically expressed as follows:

$U=mgh$

Where:

$m=60 kg$ is the mass of the skater

$g=9.8 m/s^{2}$ is the acceleration due gravity

$h=4 m$ is the skater's current height

Solving:

$U=(60 kg)(9.8 m/s^{2})(4 m)$

$U=2352 J$
