Gravitational potential energy homework

[rhxoehwhfh]

A 65 kg diver is standing on a diving platform 10.0 m above the water. What is the gravitational potential energy of the diver with respect to the water’s surface?

I know this one,,,
Ep = mgh
e= 65*10* 9.8
= 6370 Joules
or 6.37 kilojoules

If the diver in question 6 falls from the diving platform, what is her speed just as she strikes the water?

but I don't know how to calculate this one...

Use conservation of energy. What's kinetic energy?

 

[rhxoehwhfh]

does speed of the diver have something to do with kinetic energy?

Yes. Perhaps you should look it up.

 

[rhxoehwhfh]

Yep , you were right

Can you work it out now?
