A rope with weight per unit length of 0.1 lb/ft is lifted at a constant upward speed υ0 = 8 ft/s. Treating the rope as inextensible, determine the force applied to the top end of the rope after it is lifted 9 ft. Assume that the top end of the rope is initially at rest and on the floor. In addition, disregard the horizontal motion associated with the uncoiling of the rope.
