A driver is traveling at a speed of 72 km/h in car A when he looks down to text a friend that he is running late. Just before he looks down, he is 80 m from an intersection, and a bicyclist, B, traveling at a constant speed of 8 m/s is 32 m from that same intersection. The light turns red during the 3 s text, and when the driver looks up, he hits the brakes, causing a constant deceleration of 5 m/s2. Determine (a) the distance between the car and the bike when the bike reaches the center of the intersection, (b) the velocity that the car appears to have to the cyclist at this time, (c) where the car stops.
