Neco Model Questions Vol1 2017 Physics Question 8
Practice objective / multiple choice question 8 from the 2017 Neco Model Questions Vol1 Physics examination.
A diagram shows a \(30^{\circ}\) inclined plane of length \(5.0\ \text{m}\). A block of mass \(4.0\ \text{kg}\) rests on the plane and is connected by a light, inextensible string over a frictionless pulley at the top of the incline to a hanging mass of \(2.7\ \text{kg}\). The coefficient of kinetic friction between the block and the plane is \(\mu_k = 0.20\). The system moves up the incline at constant speed. If the block travels a distance of \(3.0\ \text{m}\) along the plane in \(6.0\ \text{s}\), calculate the power developed by the system (in watts, to two significant figures).
