A car with mass m = 1000 kg completes a turn of radius r = 960 m at a constant speed of v = 21 m/s. as the car goes around the turn, the tires are on the verge of slipping. assume that the turn is on a level road, i.e. the road is not banked at an angle.
what is the numeric value of the coefficient of static friction, μs, between the road and tires?
