Question: A 1 0 - meter rope is lying on the floor and has a mass force of 3 0 N . The left end of

A $10 -$ meter rope is lying on the floor and has a mass force of $30$ N $.$ The left end of the rope is lifted as indicated in the picture below. The pully makes the lifted part of the rope perpendicular to the floor and there is no friction between the rope and the floor. How much work is required to raise one end of the rope to a height of $5$ meters?
