In wandering, a grizzly bear makes a displacement of 1581 m due west, followed by a displacement of 3386 m in a direction 33.0° north of west. What are
(a) the magnitude and
m
(b) the direction of the displacement needed for the bear to return to its starting point? Specify the direction relative to due east.
°

A football player runs the pattern given in the drawing by the three displacement vectors A, B, and C. The magnitudes of these vectors are A = 5 m, B = 12.0 m, and C = 20.0 m. Using the component method, find the magnitude and direction of the resultant vector A + B + C.

A golfer, putting on a green, requires three strokes to "hole the ball." During the first putt, the ball rolls 5.7 m due east. For the second putt, the ball travels 2.9 m at an angle 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?
Magnitude
