Question

Transcribed Image Text:As you are riding in a 1650-kg car, you approach a
N7M.8
hairpin curve in the road whose radius is 50 m. The road-
bed is banked inward at an angle of 10°
(a) Suppose the road is very icy, so that the coefficient of
static friction is essentially zero. What is the maximum
speed at which you can go around the curve?
(b) Now suppose the road is dry and that the static friction
coefficient between the tires and the asphalt road is 0.6.
What is the maximum speed at which you can safely
go around the curve?
