Homework Help: Physics

Posted by Alex on Monday, May 19, 2008 at 2:03pm.

6) If a flea has a mass of 2.0x10^2 micrograms jumps vertically to a height of 65mm and 75% of the energy comes from elastic potential energy stored in the protein, determine the initial quantity of elastic potential energy.

drwls said to use:
(1/2)M g H = (0.75)E where E is the potential energy stored in protein and H is the height that the flea can jump.

I don't understand how that would work. Also would you convert 2.0x10^2ug to kg?
