Neco Model Questions Vol1 2018 Physics Question 7
Practice objective / multiple choice question 7 from the 2018 Neco Model Questions Vol1 Physics examination.
A compound pulley system consists of two identical movable pulleys and one fixed pulley. The rope is pulled vertically upward with a force \(F\). Each movable pulley reduces the tension in the rope segment that leaves it to 90 % of the tension that enters it (i.e., \(T_{out}=0.9\,T_{in}\)). A load of mass \(50\ \text{kg}\) is attached to the rope. Determine the minimum pulling force \(F\) required to lift the load at constant speed. Take \(g=9.8\ \text{m s}^{-2}\).
