A car traveling at 28.0 m/s28.0 m/s hits a bridge abutment. A passenger in the car, who has a mass of 66.0 kg, 66.0 kg, moves forward a distance of 56.0 cm56.0 cm while being brought to rest by an inflated air bag. Assuming that the force that stops the passenger is constant, what is the magnitude? F of this force?

    The answer to your question is: F = 924 N

    Explanation:

    Data

    v = 28 m/s

    m = 66 kg

    d = 56 cm

    F = ?

    Formula

    v = d/t

    a = v/t

    F = ma

    Process

    t = d/v = 56 / 28 = 2 s

    a = v/t = 28 / 2 = 14 m/s²

    F = 66 (14) = 924 N
