A car of mass m travels along the cloverleaf interchange. The position of the car is given by where b = 240 m, and t0 = 12 s is the time of travel between O and A. Determine the smallest coefficient of friction between the tires and the road that would prevent the car from skidding at A (note that t = t0 when the car is at A)
