Consider the motion of a bicycle with air drag included. We saw how to deal with the motion on a hill in connection with Figure 4.33. Now assume the bicycle is coasting on level ground and is being pushed along by a tailwind of 4.5 m/s (about 10 mi/h). If the bicycle starts from rest at t = 0, what is the acceleration of the bicycle at that moment? Assume there are no frictional forces (e.g., from the bicycle’s tires or bearings, or any other source) opposing the motion of the bicycle.
