1. The problem statement, all variables and given/known data 2. Relevant equations 3. The attempt at a solution a) I think I just have to work out the potential energy and the maximum kinetic energy would is the same? c) Once I've found the kinetic energy, I'm able to work out velocity. Would the velocity be the maximum speed? c) I think I can take the PE from A and the PE C and take them away from each other. With this number I'd have the KE of C which i'd work out velocity with?
