A car travels around a circular turn of radius 50 meters while maintaining a constant speed of 15m/s

find the minimum value for the coefficient of friction necessary to keep the car on the road

in icy conditions, the coefficient of friction drops to 0.15, Now find the maximum safe speed for taking the turn.
