    B. 34.78 m/s

    Explanation:

    Momentum of a body or an object is given as the product of its velocity and its mass.

    Therefore;

    Momentum = velocity x mass

    But; velocity = ? mass = 115 kg, momentum = 4,000 kgm/s

    Thus; velocity = momentum/mass

    = 4,000/115

    = 34.78 m/s
