11. The world's largest flag, which was manufactured in Pennsylvania, has a length of 154 m
and a width of 78 m. The flag's mass is 1.2410³ kg, which may explain why the flag has never
been flown from a flagpole. Suppose this flag is being pulled by two forces: a force of
8.00 x 10³ N to the east and a force of 5.00 x 103 N that is directed 30.0° south of east. How
much work is done in moving the flag 20.0 m directly south?
