A Karwa taxi and a Karwa bus are driving at speeds of 64.8 km/h for the car, and 68.4 km/h for the bus. They approach a frictionless roundabout and take a path of radius 119 m. If the roundabout is banked at angle of 16o with the horizontal, then what will happen to both vehicles? A) The Bus will skid, but the car will not. B) The car will skid, but the bus will not. C) Since skidding does not depend on the mass of the vehicle, both will not skid. D) Since there is no friction, both will skid. E) Cannot determine the answer because we do not know the masses of the vehicles
