how do i find kinetic energy?

Question

Fred is goin 2 Mexico where he jumps off a 27m cliff above the ocean. His mass is 80kg. what is his kinetic energy after fallin 17m

Answer 1

That's a long way to go to jump off a cliff!

KE final = PE initial = m*g*h

Assuming he is n ot moving when he jumps off the cliff(hard to jump off a cliff without moving!)
