    Answer:

    Force is zero.

    Explanation:

    According to the Newton’s second law, when an object is moving with an acceleration the force acting on the object is directly proportional to the rate of change of momentum of the object.

    F = m a

    if the object is moving with uniform velocity, the acceleration is zero, and thus, the force is also zero.
