    Answer: If a force on an object is aimed in the direction of the object's velocity, the force does positive work (b).

    Explanation:

    Hi, the answer is oprion b. positive work.

    If a force on an object is aimed in the direction of the object's velocity, the force does positive work.

    An object's kinetic energy will only change if the force acting on the object changes the object's speed. This will only happen if there is a component of the force in the direction that the object moves.

    So, A force will do work only if the force has a component in the direction that the object moves.
