Consider this traffic problem that is played out in many communities everyday! A car is cruising down the highway of life @ 25m/s in a 3-m long compact car when he comes upon an intersection with a stop sign. At the instant that he is 45 m away from the entrance to the intersection he spots a 4-m long limousine traveling @ 10m/s approaching the intersection from the right perpendicular to him and they are 15m from the entrance to the intersection with NO STOP SIGN Now comes the dilemma: should he "step on it" and accelerate at +5m/s/s or should he brake and decelerate @ -6m/s/s n order to avoid a collision? The intersection is 20m wide in both directions and the cars reaction time is 0.6s.
