Question

Danny Diver weighs 500 N and steps off a diving board 10 m above the water. Danny hits the water with kinetic energy of what?

Answer 1

5000J

Explanation:

All the gravitational potential energy is transferred into kinetic energy. (Because the final height is zero)

`GPE = mgh` (where `mg` = weight) and (`h` = height)

`GPE = 500N * 10m`

`GPE = 5000J`

And GPE initial = KE final, so KE = 5000J
