A car exciting the highway moving at 27 m/s slows down at the rate of 3.5 m/s^2 to a final velocity of 18 m/s. Calculate the distance the car travels while braking?
the velocity changes by 9 m/s (27 - 18)
this takes approx. 2.6 s (9 / 3.5)
the average velocity is 22.5 m/s
___ (27 + 18) / 2
the distance traveled is velocity multiplied by time
