A bicyclist who has a mass (including their bike) of 85 kg is racing around a track. The radius of curvature of the track is 20 m. The bicyclist’s linear velocity is 17 m/s. Given the bicyclist is at a constant speed, staying level (not going up or down, therefore no vertical acceleration), what angle does the track need to be banked so that NO frictional force is required to keep their circular path?
