You are driving through town at 13 m/s when suddenly a car backs
out of a driveway in front of you. You apply the brakes and begin
decelerating at 3.2 m/s.

How much time does it take you to stop?

Answer:

t = 4.06 s

Explanation:

Formula

a = v₂ - v₁ / t

a = -3.2 m/s²

v₂ = 0 because the car will stop

v₁ = 13 m/s

then we clear time from the equation

t = v₂ - v₁ / a

and we substitute the values

t = 0 - 13 / -3.2 = -13/-3.2 = 4.06 s
