    5000000 kg m^2 / s

    Explanation:

    mass of car, m = 1000 kg

    speed of car, v = 50 m/s

    radius of circular track, r = 100 m

    When a body is revolving around a circular track is experiences an angular momentum which is equal to the product of linear momentum and the radius of path.

    The angular momentum of the car is given by

    L = m v r

    L = 1000 x 50 x 100 = 5000000 kg m^2/s
