    B) the weight of the object and the frictional force on it before it reaches its terminal velocity
    C) its acceleration after it reaches its terminal velocity
    D) the resultant force on it when it moves as its terminal velocity

    3) A parachutist of mass 70kg supported by a parachute of mass 20kg reaches a constant speed
