A motorist suddenly notices a stalled car and slams on the brakes, negatively accelerating at 6.2 . Unfortunately this isn't enough, and a collision ensues. From the damage sustained, police estimate that the car was going 16 at the time of the collision. They also measure skid marks 36 long.

(b) How much time elapsed from the initial braking to the collision? Thank you
