Four forces act on a hot-air balloon, F_1 is upward at 4600 N, F_2 is left at 1450 N, F_3 is right at 850 N, and F_4 is downward at 3600 N.
____ N at _____ degrees clockwise from F_2.
ok, left: 1450-850= 600N to the direction of F2
now upward: 4600-3600=1000N down.
Resultant= sqrt (600^2+1000^2) at an angle downward from f2 of arctan(1000/600)
so the angle clockwise then will be 360-that angle downward.
