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?

Respuesta :

Answer: 2352 J

Explanation:

A body's gravitational potential energy [tex]U[/tex] depends on its position and is mathematically expressed as follows:

[tex]U=mgh[/tex]

Where:

[tex]m=60 kg[/tex] is the mass of the skater

[tex]g=9.8 m/s^{2}[/tex] is the acceleration due gravity

[tex]h=4 m[/tex] is the skater's current height

Solving:

[tex]U=(60 kg)(9.8 m/s^{2})(4 m)[/tex]

[tex]U=2352 J[/tex]
