Gce Model Questions Vol1 2017 Physics Question 43
Practice objective / multiple choice question 43 from the 2017 Gce Model Questions Vol1 Physics examination.
The diagram shows a uniform ladder of length \(4.0\ \text{m}\) and mass \(12\ \text{kg}\) leaning against a smooth vertical wall, making an angle of \(70^{\circ}\) with the ground. A person of mass \(70\ \text{kg}\) stands \(1.5\ \text{m}\) up the ladder from the base. The ground is rough with coefficient of static friction \(\mu_s\). Determine the minimum value of \(\mu_s\) required to prevent the ladder from slipping.
