    Acceleration of cheetah is 10 m/s²

    Explanation:

    We have equation of motion v = u + at

    Initial velocity, u = 0 m/s

    Final velocity, v = 50 miles/hr = 80 km/hr = 22.22 m/s

    Time, t = 2.22 s

    Substituting

    v = u + at

    22.22 = 0 + a x 2.22

    a = 10 m/s²

    Acceleration is 10 m/s²

    Acceleration of cheetah is 10 m/s²
