I don't understand what your question really is,. since you already have a plot within the Manipulate with the Mass, Gravity, Initial Velocity, and Height as control parameters.

What exactly do you want to do differently from that?  Are you asking how to use the Mathematica Plot function (or perhaps ListLinePlot, if you insist on discrete values of time) instead of your Graphics construct? If so, then you would add the Disk within an Epilog option within that Plot or ListLinePlot.
