    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...

    A car drives around a flat 119 m radius circular track at 20 m/s. Assume that this speed is the maximum speed that the car can have without out "skidding out" of the curve.The car moves into the next curve. The radius of this new curve is twice as great as the previous. Assume the coefficient of static friction has not changed. Calculate the car's maximum speed in this curve. m/s

    A car travels around flat, un-banked, circular track with a maximum speed of 20 m/s. If the coefficient of friction between the car tires and the track is 1.0, and the normal force between the car and the track is due to the weight of the car (no aerodynamic effects), what is the radius of the track?

    3. A racecar drives along a circular track of radius 55m at a constant speed. The curve is banked 30 and the coefficient of static friction between the car and the tires is . ° μ .7 s = 0 a. Without knowing the speed of the car, is it possible to know what the direction of friction is? Explain your reasoning. b. What is the maximum speed the car can go without skidding?

    A car is safely negotiating an unbanked circular turn at a speed of 29 m/s. The road is dry, and the maximum static frictional force acts on the tires. Suddenly a long wet patch in the road decreases the maximum static frictional force to one-sixth of its dry-road value. If the car is to continue safely around the curve, to what speed must the driver slow the car? m/s

    A car moving with a constant speed of 85 km/h enters a circular, flat curve with a radius of curvature of 0.40 km. If the friction between the road and the car’s tires can support a centripetal acceleration of 1.25 m/s2, without slipping, does the car navigate the curve safely, or does it fly off the road?
