8. We label the displacement vectors GA,GBand GC(and denote the result of their vector sum as Gr). We choose eastas the ˆidirection (+xdirection) and northas the ˆjdirection (+ydirection). We note that the angle between GCand the xaxis is 60°. Thus, () ()ˆ(50 km)iˆ(30 km) jˆˆ(25 km) cos 60i + (25 km)sin 60jABC===°°GGG(a) The total displacement of the car from its initial position is represented by (62.5 km)i
