You use a cord and pulley to raise several 100 lb boxes up to a loft, moving each box at a constant speed. You raise the first box slowly. If you raise the second box more quickly (but still at a constant speed) up to the loft, what is true about the force exerted by the cord on the box while the box is moving? O The cord exerts more force on the fast-moving box. The cord exerts less than 100 lb force for the slower box. The cord exerts more than 100 lb force to keep the box moving at faster pace. O While you need bigger force to start the box moving, once it is moving upward the cord exerts the same 100 lb force as the first (slower) box
