    Answer:

    Explanation:

    Given the following data;

    Mass of child = 23 kg

    Mass of bike = 5.5 kg

    Velocity = 4.5 m/s

    Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.

    Mathematically, momentum is given by the formula;

     Momentum = mass * velocity

    To find the momentum of each of them;

    I. Momentum of the child

    Momentum C = mass * velocity

    Momentum C = 23 * 4.5

    Momentum C = 103.5 Kgm/s

    II. Momentum of the bike

    Momentum B = mass * velocity

    Momentum B = 5.5 * 4.5

    Momentum B = 24.75 Kgm/s

    Hence, we can deduce from the calculations that the momentum of the child is greater than that of the bike because of the higher mass possessed by the child.
