A block of mass \(5\ \text{kg}\) is lifted by a system of two ideal pulleys: a fixed pulley attached to the ceiling and a movable pulley attached to the block. The rope passes over the fixed pulley, under the movable pulley, and the free end is pulled upward with a force \(F\). (a) Find the magnitude of \(F\) required to lift the block at constant speed. (b) If the pulling force is increased so that the block accelerates upward at \(2.0\ \text{m s}^{-2}\), find the new required pulling force.
