    For the second question, it's like the PRS example in class. You have to analyze the system first as a point particle system, then as a real system. SO: PP- delta E sys = W surr, pp delta K trans = W surr = F (dot) delta r CM delta K trans = Fx Real - delta E sys = W surr, real delta K trans +...
