                                      (A) A man pushes on a large 25 Kg block of ice on a frictionless 
                                    surface. If he applies 50 N of force to the block, solve for the 
                                    following unknowns.

         Now, Imagine there is friction between the block and the ice. The coefficient of friction is 0.2
