    Answer:

    m = 0.01 kg

    Explanation:

    Given that,

    Momentum of the marble, p = 0.15 kg-m/s

    Speed of the marble, v = 15 m/s

    We need to find its mass. We know that,

    Momentum, p = mv

    Where

    m is the mass

    m=\dfrac{p}{v}\\\\m=\dfrac{0.15}{15}\\\\m=0.01\ kg

    So, the mass of the marble is equal to 0.01 kg.
