Question

A diver who weighs 500 N steps off a diving board that is 10 m above the water. The diver hits the water with kinetic energy of 8) _______ A) 10 J. B) 500 J. C) 5000 J. D) more than 5000 J. E) 510 J.

Answer 1

C) 5000 J

Step-by-step explanation:

when diver is at some height , he is having some energy in the form of potential energy. when he dives, his potential energy is converted into kinetic energy . so kinetic energy and potential energy are equal.

Kinetic energy of diver = potential energy of diver

= mgh

= 500 x 10

= 5000 J .
