When a car is rounding a bend on a flat road, the centripetal force is provided by the friction petween the road and the tires. During a wet day the friction disappears and it becomes difficult pr even dangerous to negotiate such a bend. This is overcome by banking the road as shown pelow. centre of circular path 200 m a) For a bend of radius 200 m, find the angle 0 such that a 1500 kg car moving with speed 80 km h' can negotiate the bend without sideward friction providing for the centripetal force. b) A 2000 kg car is now moving on the same wet bend at 80 km h'. State with a reason if the car is able to negotiate the bend with skidding.
