At a picnic, there is a contest in which hoses are used to shoot water at a beach ball from three directions. As a result, three forces act on the ball, F1, F2, and F3 (see the drawing). The magnitudes of F1 and F2 are F = 21.0 newtons (N) and F2 = 75.0 N. Determine (a) the magnitude of F3 and (b) the angle & such that the resultant force acting on the ball is zero. (a) Number i Units (b) Number i Units 60.0 8 N Fi W E 13 $ 12 SUPPORT
