A truck traveling at 50 km/hr approaches a car stopped at a red light. When the truck is 100 m from the car, the light turns green and the car immediately begins to accelerate at 2 m/s2 to a final speed of 100 km/hr.

A) • How long does it take for the car to reach its maximum speed?

B)During this time, how far does the car travel?

C)What is the distance between the truck and the car 20 seconds after the light turns green ? (assume there isn’t another traffic light yet)
