You are to make four straight-line moves over a flat desert floor,starting at the origin of an xy coordinatesystem and ending at the xy coordinates(-145 m, 36 m). The xcomponentand y component of your moves are the following,respectively, in meters: (20 and 60), then(bx and -70), then(-20 and cy), then (-63 and -75).
a) What is component bx?b) What is component cy?c) What is the magnitude of the overall displacement?d) What is the angle of the overall displacement?
