Question

Questions to consider:

1. If the skater has a mass of 60 kg, what is her gravitational potential energy at the top of the 4 m high
half-pipe?

Answer 1

Answer: 2352 J

Step-by-step 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`
