On a banked race track, the smallest circular path on which cars can move has a radius of 111 m, while the largest has a radius of 157 m, as the drawing illustrates. The height of the outer wall is 15.7 m. Find (a) the smallest and (b) the largest speed at which cars can move on this track without relying on friction. I am having trouble finding an answer because I wasnt given any angles. Please help me in any way that you can. Thank you VERY much!
