Neco Model Questions Vol1 2018 Physics Question 38
Practice objective / multiple choice question 38 from the 2018 Neco Model Questions Vol1 Physics examination.
A block of mass \(10\ \text{kg}\) is lifted vertically at constant speed by a simple block‑and‑tackle system consisting of one fixed pulley and one movable pulley. The rope is attached to the ceiling, passes under the movable pulley attached to the load, then over the fixed pulley, and the operator pulls the free end. The system operates with an overall efficiency of \(80\%\). Calculate the magnitude of the force the operator must apply (in newtons, to two decimal places).
