Neco 2021 Further Mathematics Question 4
Practice objective / multiple choice question 4 from the 2021 Neco Further Mathematics examination.
A block of mass \(5\,\text{kg}\) slides down a rough incline that makes an angle of \(30^{\circ}\) with the horizontal. The length of the incline is \(2\,\text{m}\) and the coefficient of kinetic friction is \(0.20\). At the foot of the incline the block compresses a spring of spring constant \(800\,\text{N\,m}^{-1}\) and comes to rest. Assuming \(g=9.8\,\text{m\,s}^{-2}\), find the maximum compression of the spring (in metres, correct to three significant figures).
