Gce Model Questions Vol1 2022 Physics Question 1
Practice objective / multiple choice question 1 from the 2022 Gce Model Questions Vol1 Physics examination.
A motor drives a small pulley of radius \(0.10\) m rotating at an angular speed of \(120\) rad s\(^{-1}\). A rope is wound on this pulley and passes over a larger pulley of radius \(0.30\) m that is attached to a load weighing \(200\) N. Assuming the system operates at \(90\) % efficiency, calculate the electrical power that must be supplied to the motor (in kilowatts, to two decimal places).
