10. [-/6 Points] DETAILS SERPSE10 3.4.OP.013. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER It takes a golfer a total of three strokes to put the ball in the hole. The displacements of the three strokes are as follows: d, = 4.00 m the north, d = 1.90 m northeast, and d; = 1.10 m at 0 = 25.0 west of south, as shown in the figure. If the golfer had made the hole in a single shot, what would be the displacement of the ball? (Assume the positive y- and x-axes are in the north and east directions, respectively. Give the magnitude of your answer in meters and the direction in degrees north of east.) d2 W magnitude m direction north of east Need Help? Read It Submit Answer11.

(Take the +x direction to be to the right.) (a) the magnitude and direction of the vector D = A + B + C magnitude X Note that all three vectors lie in the xy plane so the sum of these vectors will also lie in the xy plane. m direction X Use a piece of graph paper to carefully represent the sum of these vectors and use your drawing to check that your angle is reasonable. counterclockwise from the +x axis (b) the magnitude and direction of E = -A - B + magnitude m direction . counterclockwise from the +x axis Need Help?
