Waec Model Questions Vol1 2019 Physics Question 25
Practice objective / multiple choice question 25 from the 2019 Waec Model Questions Vol1 Physics examination.
Block A (mass \(4\ \text{kg}\)) rests on a rough horizontal table with a coefficient of kinetic friction \(\mu_k = 0.20\). Block B (mass \(6\ \text{kg}\)) lies on a smooth incline of \(30^{\circ}\) that meets the table at a smooth pulley. The two blocks are connected by a light inextensible string over the pulley. A horizontal force \(F\) is applied to block A to the right. Determine the minimum magnitude of \(F\) required to start moving the system (i.e., to overcome friction on block A). Give your answer in newtons to one decimal place.
