Question

Humpty Dumpty (12 kg) sat on a wall (2 m high). What was his potential energy, before his great fall?
A. 235.2 J B. 235.2 N C. 24 J D. 246.1 W

Answer 1

I think it would be B. P.E.=mgh, the mass is 12g, gravitational force is 9.8, and the wall is 2 meters high, so multiply it all and get 235.2.

Answer 2

It would be 24J because there's no energy.
