Igcse Model Questions Vol1 2024 Physics Question 33
Practice objective / multiple choice question 33 from the 2024 Igcse Model Questions Vol1 Physics examination.
A block‑and‑tackle system is used to lift a load weighing \(200\ \text{N}\). The system provides a mechanical advantage of \(4\). An operator pulls the rope with a constant force of \(60\ \text{N}\) and in doing so pulls the rope through a distance of \(2.0\ \text{m}\) in \(5.0\ \text{s}\). Assuming the rope is mass‑less and the pulleys are frictionless, (a) calculate the average power output of the lifting system in watts, and (b) determine the efficiency of the system as a percentage.
