I can find the energy in Coulombs, but I don't know where to go. Step by step would be helpful so I can do this on my own, next time.
"How high would you have to drop a 2 kg mass to have the same energy as a 30microfard capacitor charged to 200 v?"

"I can find the energy in Coulombs"
A coulomb is a unit of charge, not energy.
The energy stored on a capacitor can be calculated with
U = 1/2 CV^2
From there, set it equal to gravitational potential energy,
mgh = 1/2 CV^2
And solve for h. The rest is algebra.
