Below is a top view of the circular course. The black dot represents the bicycle + rider at an arbitrary instant during the race. Assume the bicyclist is traveling around the track in the counterclockwise direction. To simplify the problem, also assume that rolling friction is negligible. (This is reasonable because the contact area between the bicycle tires and the ground is often very small.) Draw a free- body diagram showing all the horizontal forces acting on the bicycle. Make a reasonable estimation of the direction of each force.
