Angle of a Banked Roadway
While reading the chapter for uniform circular motion, one of the examples details finding the angle of a banked roadway given the maximum speed and radius. The equations for forces in horizontal and vertical directions are:
(1) ncosθ=mg
(2) nsinθ=mv^2/r
where n is the normal force
Now, my question is why do we divide equation 2 by equation 1? I can't seem to wrap my head around the logic of doing this.
Thanks
