A curve of radius 106 m is banked at an angle of 11.9 . At what speed can it be negotiated under icy conditions where friction is negligible

2.On a banked race track, the smallest circular path on which cars can move has a radius of 120 m, while the largest has a radius of 173 m, as the drawing illustrates. The height of the outer wall is 11.8 m. Find (a) the smallest and (b) the largest speed at which cars can move on this track without relying on friction
