A car of length 15 ft. approaches a signalized intersection at 45 mph when the light changes to yellow. The vehicle is 300 ft. from the intersection, and the width of the intersection is 48 ft. At this distance and initial speed, determine the following. a.What is the minimal yellow time required for the vehicle to clear the intersection?b. Assuming a perception-reaction time of 1.5 seconds and a vehicle deceleration rate of 10 ft/sec2, determine if the vehicle can safely stop before entering the intersection. c.Assuming the light is yellow for 4 seconds, determine the safe action for the vehicle if one exists. Does a"dilemma" exist for this driver? i. Attempt to clear ii. Attempt to stop
