At the same time, a truck, moving at a constant speed of 10ms-2, passes the traffic light, which just turns green, and overtakes the car. Since the car moves with increasing speed, it will overtake the truck some times later.
(a) At what distance from the traffic light will the car overtake the truck?
(b) What is the speed of the car at that instant? |
