    Initial velocity of Cheetah (V1) = 0.0 mi/hr

    Final velocity of Cheetah (V2) = 70 mi/hr

    Time for acceleration (T) = 3 seconds.

    We know the formula

    Accelaration (A) = Velocity/Time

    So

    A = (V2 - V1) / T

    = (70 - 0) / 3

    = 70/3

    = 23.33mph/sec

    So the accelaration of the Cheetah is 23.33 mph/sec.
