i thought i can write this in the off topic are since i have no place to write this potential energy problem that i have a problem with.

IN 1993, a cricket named Jimmy set the world record for leaping at the insect Olympics in Athens, Greece. THe gravitational potential energy associated with Jimmy's jump was 30j. Jimmy's mass was 1.531 kg. How high did Jimmy jump?

It's also one of the most trivial maths mechanics/physics questions to answer.

Sorry, no help from me either. One hint: look at the formula sheet you've been given, or in your textbook, or in your class notes.

Hmmm.. it has been 20 years since I was in school studying this... Maybe formula E=mgh helps you... If I recall it correctly?
