Calculating Kinetic Energy for Solving PE and KE Problems

[I NEED HELP]

Energy Question?

OK let's say that PE=15000 or 11250 J (J=Joules) how would you find out what the KE is?

just want to find out how to get the Kinectic Energy?

You need to show equations and an attempt at the answer

OK let's say that PE=15000 or 11250 J (J=Joules) how would you find out what the KE is?

just want to find out how to get the Kinectic Energy?

Saying that potential energy is 11250J is meaningless really.
Is there some sort of problem associated with the potential energy? A body falling? Something of that sort?

ok then let's say it's a body falling how do i answer this...i don't want you to give me the answer i need help so i can understand this and solve it to get the answer on my own...
