3. The xand the ycomponents of a vector Galying on the xyplane are given by cos ,sinxyaaθθ==where||=Gis the magnitude and θis the angle between Gaand the positive xaxis. (a) The xcomponent of Gais given by ax= 7.3 cos 250° = – 2.5 m. (b) and the ycomponent is given by ay= 7.3 sin 250° = – 6.9 m. In considering the variety of ways to compute these, we note that the vector is 70° below
