As soon as a traffic light turns green, a car speeds up from rest to 52 mi/ h with constant acceleration 10 mi/ h-s. In the adjoining bike lane, a cyclist speeds up from rest to 23 mi/ h with constant acceleration 12 mi/ h-s. Each vehicle maintains constant velocity after reaching its cruising speed.
