You are driving through town at 19 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/s2 . Part A How much time does it take you to stop?

Answer :

Answer:

Time taken to stop = 5.94 seconds

Explanation:

We have equation of motion, v = u + at

Final velocity , v = 0 m/s

Initial velocity, u = 19 m/s

Acceleration, a = -3.2 m/s²

time, t = ?

Substituting

            0 = 19 - 3.2 x t

            t = 5.94 s

Time taken to stop = 5.94 seconds
