Intro physics question

  • #1
You are driving along the New York State Thruway in
a line of cars all travelling at a constant speed of 106.8 km/hr.
The car in front of you applies its brakes for maximum accelera-
tion. You then apply your brakes to achieve the same maximum
acceleration after only a 1 s delay due to reaction time. What
distance behind the car in front of you must you be to avoid a
collision?

When I want to make MY car accelerate, I hit the gas. I find it very weird that you hit the brakes to accelerate.
