Gce Model Questions Vol1 2022 Physics Question 12
Practice objective / multiple choice question 12 from the 2022 Gce Model Questions Vol1 Physics examination.
A block of mass \(5.0\ \text{kg}\) starts from rest at the top of a smooth incline that is \(8.0\ \text{m}\) long and makes an angle of \(30^{\circ}\) with the horizontal. At the bottom of the incline the block reaches a rough horizontal surface of length \(4.0\ \text{m}\) where the coefficient of kinetic friction is \(\mu_{k} = 0.20\). The block just comes to rest at the far end of the rough surface. Calculate the work done by the friction force on the block while it moves over the rough surface. State your answer in joules (negative sign indicates that friction does negative work).
