You are to make four straight-line moves over a flat desert floor, starting at the origin of an xy coordinate system and ending at the xy coordinates (– 140 m, 30 m). The x component and y component of your moves are the following, respectively, in meters: (20 and 60), then (b, and –70), then (–20 and cy), then (–60 and –70).What are

(a) Component bx and

(b) Component cy? What are?

(c) The magnitude and

(d) The angle (relative to the positive direction of the x axis) of the overall displacement?
