28 @ S45W = (-19.8,-19.8)
56 @ E = (50,0)
84 @ E53N = (50.5,67.1)
Add them up to get (80.7,47.3)
So, we need (-80.7,-47.3) to get back to (0,0), a displacement of 93.5 m
An ice skater skates 28 m southwest, then
56 m east, and finally 84 m in a direction
50.3
◦ north of east.Find the magnitude of the displacement required to bring the skater back to her starting
point.
