Question

A race car accelerates uniformly as it leaves the pit area,going from rest to 330 km/h in asemicircular arc with a radius of 200m.
Determine the radial acceleration of the car at this time. m/s2
If the curve were flat, what would the coefficient of staticfriction have to be between the tires and the roadbed to providethis acceleration with no slipping or skidding?

Explanation / Answer

       Given that the velocity is v =330 km/h = 91.66 m/s        Radius is r = 200 m -------------------------------------------------------------       Radial acceleration is ac= v2/ r                                          =-------- m/s2       The centripetal force is f =mac                                  mg = mac           = ac / g                                            = ---------
