Question

A car travels around a circular turn of radius 50 meters while maintaining a constant speed of 25 m/s. A. Find the minimum value for the coefficient of friction necessary to keep the car on the road. B. In icy conditions, the coefficient of friction drops to 0.10. Now find the maximum safe speed for making the turn. C. If the flat roadway were replaced by a banked one, what angle of incline would be necessary for the car to make the turn (again in icy conditions) at this same speed without requiring the use of friction?

Explanation / Answer

A)0.5=v/r B)R=25 metres
