Igcse Model Questions Vol1 2022 Physics Question 18
Practice objective / multiple choice question 18 from the 2022 Igcse Model Questions Vol1 Physics examination.
A \(5.0\ \text{kg}\) block rests on an inclined plane that makes an angle of \(30^{\circ}\) with the horizontal. The coefficient of kinetic friction between the block and the plane is unknown. When a force of \(10\ \text{N}\) is applied parallel to the plane upward, the block moves down the plane at constant speed.\n(a) Find the coefficient of kinetic friction.\n(b) Using this coefficient, calculate the magnitude of a force parallel to the plane required to accelerate the block up the plane at \(2.0\ \text{m s}^{-2}\). Give your answer in newtons, correct to the nearest newton.
