    Answer: - 1.5m/s^2

    Explanation:

    Initial velocity V1 = 14.0 m/s

    Final velocity V2 = 5.0 m/s

    Time taken = 6.0s

    The car's acceleration = ?

    Since acceleration is the rate of change of velocity per unit time

    i. e acceleration = (V2 - V1) / T

    Acc = (5.0 m/s - 14.0 m/s) / 6.0 s

    Acc = (-9.0m/s) / 6.0s

    Acc = - 1.5m/s^2 (the negative acceleration means the car is slowing down)

    Thus, the cars acceleration is - 1.5m/s^2
