SUMMARY
A car accelerating uniformly from rest at 2.50 m/s² west reaches a velocity of 20.0 m/s west after 3.2 seconds. The displacement during this time is calculated using the formula xf = 1/2(vf + vi)t, resulting in a total distance of 32 meters west. The calculations confirm that the time taken to reach the final velocity is indeed 3.2 seconds, validating the use of kinematic equations in this scenario.
