I am wondering about quality of online courses. It seems more an more are interested in the answer, not the process.
A truck is stopped at a stoplight. When the light turns green, it accelerates at 2.2 m/s2. At the same instant, a car passes the truck going 11 m/s. Where and when does the truck catch up with the car?
