An engineer wants to design a circular racetrack of radius r such that cars of mass M can go around the track at speed u without the aid of friction or other forces other than the perpendicular contact force from the track surface Find an expression for the required banking angle 0 of the track, measured from the horizontal. Express the answer in tan terms of M, r, u, and g rg Suppose the race cars actually round the track at a speed W > u. What additional radial force F, is required to keep M(W-u)2 Mu F = r the cars on the track at this speed? Express the answer in terms of M, r, u, W, and g.
