... (d) Plugging = 23° into the above result for F, with s = 0.42 and W = 180 N, yields F 70 N . 44. The magnitude of the acceleration of the car as it rounds the curve is given by v2/R, where v is the speed of the car and R is the radius of the curve. Since the road is horizontal, only the frictio ...
