    It will take 0.014 hour or 50.4 seconds to reach a speed of 120 km/h

    Explanation:

    We are given:

    Initial speed of car = Vi = 50 km/h

    Final Speed of car = Vf = 120 km/h

    Acceleration of car = a = 5000 km/h²

    Time taken = t = ?

    Using 1st equation of motion;

    Vf = Vi + at

    t = (Vf - Vi) / a

    t = (120 km/h - 50 km/h) / 5000 km/h²

    t = 0.014 h

    t = (0.014 h) (3600 sec/1h)

    t = 50.4 sec
