A car capable of a constant acceleration of
3.72 m/s
2
is stopped at a traffic light. When
the light turns green, the car starts from rest
with this acceleration. At the very same moment, a truck traveling with constant velocity
13.8 m/s passes the car.
As the car’s velocity increases, it will eventually move faster than the truck and later
overtake it. How far from the light will the
car catch up with the truck?
Answer in units of m.
