A circus act features a motorcycle that is driven around the inside of a cylindrical path, in a plane parallel to the ground, executing uniform circular motion while staying at the same horizontal height.

The motorcycle maintains a constant speed of$|$v$|=16$ m$/$s$,$ and the cylindrical track has a radius of R $=19$ m$,$ with a coefficient of static frictions$=0\mathrm{.}8$ between the track and the motorcycle's tires. The magnitude of the friction force between the motorcycle and the track is f $=1900$ N$.$
