1)A car of mass 1200 kg can take turn on a circular level road of radius of 150 m with a max speed of 15m/s without skidding. Find the force of fricion and the coefficient of friction between the tyres of the car and the road ?
2)A cyclist speeding at 18 kmph on a level road takes a sharp circular turn of radius 3m without reducing the speed. The coeffitient of static friction between the tyres and the road is 0.1. Will the cyclist slip while turning?
