## Main Question or Discussion Point

I need to work out the impact energy for three different drop heights. Im 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 im now trying to improve my maths before commiting to a HNC in mechanical engineering.
