Answer:
C) 5000 J
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 .
