EXAMPLE: A Car from rest, Accelerates to 50 km/hr as Fast as Possible -Predict its Acceleration in m/s

- 50 km/hr = 50 km /hr / 3.6 = 13.88... m/s -You have to Guess the Time it took for it to reach 13.88 m/s, so pick a Number that is Sensible - 2 Seconds in this Case -So we use Acceleration = Change in Velocity / Time Taken -Acceleration = 13.89 m/s / 2 = 7 m/s² [1 Sig Figure]
