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?

Jason, a 60 kg cyclist, is pedaling his bike at a good clip, using a total energy of 400 W. As he exercises, his body will start to warm up, and he will perspire to keep himself cool. 1) Assuming Jason’s pedaling has a typical 25% efficiency, by how much would his body temperature rise during 1.0 h of cycling if he had no means of exhausting excess thermal energy? 2) Assume that the only means by which his body...
