Solution A golfer, putting on a green requires three strokes to "hole the ball." During the first putt, the ball rolls 5.0 m due east. For the second putt, the ball travels 2.1 m at an angle of 20 north of east. The third putt is 0.50 m due north. What displacement (magnitude and direction relative to due east) would have been needed to "hole the ball" on the very first putt? Use components to solve this problem. Identify the three vectors. Sketch the vectors and show the vector sum. Include a coordinate system. Problem 2 Pre-Lab for LAB#3 At a picnic, there is a contest in which hoses are used to shoot water at a beach ball from three different directions. As a result, three forces act on the ball, F1, F2, and F3 (see drawing). The magnitudes of F1 and F2 are F1 = 50.0 N and F2 = 90.0 N. F1 acts under an angle of 60 with respect to the x-axis and F2 is directed parallel to the x-axis. Find the magnitude and direction of F3 such that the resultant force acting on the ball is zero. 60 F1 F3/ F2
