Neco Model Questions Vol1 2018 Physics Question 29
Practice objective / multiple choice question 29 from the 2018 Neco Model Questions Vol1 Physics examination.
A \(2\ \text{kg}\) block is pulled along a horizontal surface from \(x = 0\ \text{m}\) to \(x = 2\ \text{m}\) by a force that varies with displacement as \(F(x) = 5x^{2}\ \text{N}\), where \(x\) is in metres. The coefficient of kinetic friction between the block and the surface is \(0.2\). The block starts from rest at \(x = 0\). Determine the speed of the block when it reaches \(x = 2\ \text{m}\). Give your answer in metres per second to two decimal places.
