Question
When the brakes of a certain car are applied, a deceleration of 6.0 sec squared is produced. a) How much time will it take to bring the car to a halt from an initial speed of 110km/hr? b) How far will it travel in that time?

If the braking distance is X, and v is the initial velocity, the relationship is
T = V/a
Solve the braking time T. distance X.
For the braking distance X, use
X = Vaverage*T = (V/2)*T = V^2/(2a)
You will have to convert your
