You are driving toward a traffic signal when it turns yellow. Your speed is the legal speed limit of v0 = 55km/h; your best deceleration rate has the magnitude a = 5.18m/s2. Your best reaction time to begin braking is T = 0.75s. To avoid having the front of your car enter the intersection after the light turns red, should you brake to a stop or continue to move at 55 km/h if the distance to the intersection and the duration of the yellow light are
(a) 40 m and 2.8 s, and
(b) 32 m and 1.8s, give an answer of brake, continue, either (if either strategy works), or neither (if neither strategy works nor the yellow duration is inappropriate).
