    Acceleration of car = 3.75 ft/s²

    Explanation:

    We have equation of motion v² = u² + 2as

    Initial velocity, u = 71 ft/s

    Final velocity, v = 79 ft/s

    Displacement, s = 160 ft

    Acceleration, a = ?

    Substituting

    v² = u² + 2as

    79² = 71² + 2 x a x 160

    a = 3.75 ft/s²

    Acceleration of car = 3.75 ft/s²
