Gce Model Questions Vol1 2021 Physics Question 4
Practice objective / multiple choice question 4 from the 2021 Gce Model Questions Vol1 Physics examination.
In the diagram, a smooth inclined plane makes an angle of 30° with the horizontal and has a length of 4.0 m. A block of mass 5.0 kg rests at the top of the incline. It is attached by a light inextensible string over a frictionless, mass‑less pulley at the top of the plane to a hanging mass of 2.0 kg. The system is released from rest. When the block has moved 2.0 m down the incline, what is the instantaneous power delivered by the hanging mass? Take \(g = 9.8\) m s\(^{-2}\) and give your answer in watts to two significant figures.
