I was in class today and we flew through the relantionship with Kinetic engery and Potential engery rather quickly.(adsbygoogle = window.adsbygoogle || []).push({});

I looked it up in the book but it went over my head.

Ei = Ef

Meaning

Ei = Ef

^ ^

Kinetic intital + Potential intital = Kinetic Final + Potential Final

This relates to the following question:

A ball is dropped from a hieght of 60meters. How high above the ground will it be when one-third of its total engery is KE?

Can you tell me the the Ei = Ef means and then give me a starting point to work the problem?
