Gce Model Questions Vol1 2018 Further Mathematics Question 30
Practice objective / multiple choice question 30 from the 2018 Gce Model Questions Vol1 Further Mathematics examination.
A block of mass \(5\text{ kg}\) starts from rest at the bottom of a rough inclined plane that makes an angle of \(30^{\circ}\) with the horizontal and has length \(10\text{ m}\). The coefficient of kinetic friction is \(\mu = 0.2\). A pulling force acting parallel to the plane varies with the distance \(x\) (in metres) from the bottom as \(F(x)=20+5x\) newtons. Using the work‑energy principle, calculate the speed of the block when it reaches the top of the incline. Give your answer to two decimal places.
