I understand that E = K1 + P1 = K2 + P2, BUT,(adsbygoogle = window.adsbygoogle || []).push({});

I'm not sure when what equals what for this problem, and I could use a push start.

Projectile (mass 2.40 kg) fired from a cliff 125 m high with Vo = 150 m/s, 41.0 degrees from the horizontal. What's the kinetic and potential energy just after firing?

I have K = 27,000 J. Is this right? How can I find the potential energy if it is not P = mgh?

Thanks for the help.
