Impact energy for different drop heights

[valemark]

I need to work out the impact energy for three different drop heights. I am really struggling to get my head around it.

Am i on the right lines with this?

mgh = (1/2) mv2

Please excuse my basic knowledge, I left school 21 years ago with a D in maths, but I am now trying to improve my maths before commiting to a HNC in mechanical engineering.

My guess is that your are on the right track. If you want to make sure, start a thread in the introductory physics homework section of the forum https://www.physicsforums.com/forums/introductory-physics-homework.153/ . State the exact wording of the problem. Show your work.
