Question

Calculate the potential energy of a diver that has a mass of 45 kg and is standing on a diving board that is 15 m high.

Answer 1

Given

Mass of the diver,

`m=45kg`

The height of the board,

`h=15\text{ m}`

To find

Potential energy of a diver.

Step-by-step explanation

The potential energy is given by:

`U=\text{mgh}`

where g is the acceleration due to gravity given as:

`g=9.8m/s^2`

Putting the values we have,

`U=45*9.8*15=6615J`

Conclusion

The required potential energy is 6615J.
