cose 20° Problem 10 Refer to the diagram above. The person drags a rock across the ground at a constant speed. There is a friction force opposing the motion of the rock. The tension in the rope is 750 N. How much work is done by the friction force as the rock is dragged through a 15 m displacement? Don't forget units! 7500
