Neco 2020 Physics Question 6
Practice essay / theory question 6 from the 2020 Neco Physics examination. This question covers machines, simple machines, pulleys, mechanical advantage, work and energy, power .
The diagram shows a system of two pulleys used to lift a load. The load (weight \(W = 500\,\text{N}\)) is attached to a movable pulley. The rope passes over a fixed pulley and the effort force \(F\) is applied to the free end of the rope. When the effort end of the rope moves a distance of \(2.0\,\text{m}\), the load rises a distance of \(0.5\,\text{m}\). In an experiment the effort required to raise the load at constant speed was measured as \(150\,\text{N}\). The load is raised through its total distance of \(0.5\,\text{m}\) in \(5\,\text{s}\).
