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 = ---------
