A truck is stopped at a stoplight. When the light turns green, the truck accelerates at 2.2 m/s2. At the same instant, a car passes the truck going 12 m/s. Where and when does the truck catch up with the car?

  They go the same distance in the same time. truck: d=1/2 a t^2 car: d=12t set the distances equal 12t=1/2 a t^2 t=24/a
