A car on a flat circular track with a radius of 1.00km completes a circuit every 100.0s. (a) What is the speed of the car in mph? (b) What is the centripetal acceleration of the car in m/s2? (c) On a rainy day, the car is traveling around the track with faster and faster speed. At 72.4 mph the car loses control and slides off the track. What is the coefficient of static friction?

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

An 800. kg racecar travels on a flat circular track of radius 250 m. Assuming the car moves with a constant speed of 45.0 m/s, find (a) its angular speed, (b) the magnitude and direction of its acceleration, and (c) the minimum static coefficient of friction, between the tires and the road, that keeps the car from slipping.

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?
