Neco 2020 Physics Question 33
Practice objective / multiple choice question 33 from the 2020 Neco Physics examination.
A 5.0 kg block rests on a horizontal rough surface. It is pulled by a rope that makes an angle of \(30^{\circ}\) above the horizontal. The tension in the rope is \(10.15\ \text{N}\) and the coefficient of kinetic friction between the block and the surface is \(0.20\). The block moves at constant speed. Using the force diagram (see visual), determine (i) the magnitude of the normal reaction exerted by the surface on the block and (ii) the magnitude of the kinetic friction force.
