Gce Model Questions Vol1 2025 Physics Question 13
Practice objective / multiple choice question 13 from the 2025 Gce Model Questions Vol1 Physics examination.
The diagram shows a smooth inclined plane making an angle of \(20^{\circ}\) with the horizontal. The length of the incline is \(5.0\ \text{m}\). A block of mass \(3.0\ \text{kg}\) starts from rest at the top (point A) and slides down the plane. The coefficient of kinetic friction between the block and the plane is \(\mu_{k}=0.15\). Point D lies \(3.0\ \text{m}\) down the incline from A (as indicated on the diagram). Determine the instantaneous power supplied by the component of the block's weight parallel to the plane when the block reaches point D. Give your answer in watts, to two significant figures.
