The largest palace in the world is the Imperial Palace in Beijing, China. Suppose you were to push a lawn mower around the perimeter of a rec-
tangular area identical to that of the palace, applying a constant horizon-
tal force of 60.0 N. If you did 2.05 x 10J of work, how far would you have
pushed the lawn mower? If the Imperial Palace is 9.60 x 102 m long, how
wide is it?
