On a banked race track, the smallest circular path on which cars can move has a radius r1 = 111 m, while the largest has a radius r2 = 163 m. The height of the outer wall is 18 m.(adsbygoogle = window.adsbygoogle || []).push({});

(a) Find the smallest speed at which cars can move on this track without relying on friction.

(b) Find the largest speed at which cars can move on this track without relying on friction.

I think that I'm supposed to use this equation:

v= Square root of (r)(g)tan theta, but I don't know how to find theta?
