Q. at a picnic, there is a contest i which hoses are used to shoot water at a beach ball from three directions. as a result, three forces act on he ball, f1, f2,f3. the magnitude of f1 and f2 are f1=50 newtons and f2=90 newtons. using a scale drawing the graphical technique, determine (a) the magnitude of f3 and (b) the angle such that resultant force acting on the ball is zero.
