1) A car with mass m = 1000 kg is traveling around a circular curve of radius r = 990 m when it begins to rain. The coefficients of static friction between the road and tires is μd = 0.66 when dry and μw = 0.26 when wet. a) Write an expression for the maximum magnitude of the force of static friction Ff acting on the car if μs is the coefficient of friction. b) What is the maximum tangential...

To test the performance of its tires, a car travels along a perfectly flat (no banking) circular track of radius 101 m. The car increases its speed at uniform rate of 3.56 m/s^2 until the tires start to skid. If the tires start to skid when the car reaches a speed of 16.9 m/s what is the coefficient of static friction between the tires and the road?

A car is travelling at a flat circular track of radius 25 m and tries to go around at 40 m/sec. a) What should the coefficient of static friction be so the car won’t skid? b) Assume the same car is now travelling at a banked circular track at angle 25o , r=25 m and with same speed. What’s the value of the coefficient of static friction in order for the car not to slide down? c) What would the...
