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 (-165 m, 59 m). the x component and y component of your moves are the following, respectively, in meters: (20 and 60), then (bx 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?
