The bends on a track for car racing are semicircular and the track is banked at an angle of 280 to the horizontal. Suppose the radius of the curvature of the bends is 120 m. (20 marks) a) At what speed can a racing car and a driver of mass 800 kg take these bends even when there is no friction between the car and the track? b) If the car speed is twice of that in (a). (i) draw the free-body diagram of the car (ii) Find the value of the frictional force f.
