A car weighing 1600 kg moving with a velocity of 30 mIs retards uniformly coming to rest in 20 seconds. Calculate the 1.Motion of a car on banked road. Friction is not always reliable at circular turns if high speeds and sharp turns are involved. To avoid dependence on friction, the roads are banked at the turn so that the outer part of the road is somewhat lifted up as compared to the inner part.This is called banking of a road. The angle made by the surface with the horizontal, i.e. the angle of inclination, is referred to as the banking angle. While moving through such a curved road, the normal force acting on the vehicle has a horizontal component. This component provides the centripetal force to avoid skidding.The necessary centripetal force required to negotiate a turn by a vehicle moving along a horizontal unbanked curved road is provided by the force of friction between the wheels (tyres) and the surface of the road. Let us consider a vehicle of a mass 'm' is moving along a horizontal curved road of radius 'r' with speed 'v'.A car of mass M = 1200 kg is traveling at 65.0 km/hour and enters a banked turn covered with ice.
