How do i find potiential and kinetic energy?

Question

Example: Fred to a trip to Mexico where he jumps off a clif which is 27 m above the ocean. His mass is 80kg. How do i find his potiential energy after falling 17m

Answer 1

PE=mgh
KE=.5mv^2
PE=(80)(9.8)(10)
PE=7840j

Answer 2

IN a device there is complete complete capacity and by using this technique, the only 2 variables are potential and kinetic energies. potential energies are saved energies so on the perfect of the curler coaster, the curler coaster has the aptitude to drop to the floor, because of fact the curler coaster slides, its loses a number of its potential capacity because of fact this is not as severe as till now, yet this capacity gets transfered to kinetic capacity which relies upon on the stream of the article.
