We are not here to do your homework.  We do help ups, not hand outs.  We have our own problems to go solve (we are all volunteers on here after all).  If you want help, then show what you have tried and where you are stuck.  Altenbach and I have told you everything you need in order to solve this problem.  Give them a try and then post back with the problems you are having.
