Neco 2023 Further Mathematics Question 30
Practice objective / multiple choice question 30 from the 2023 Neco Further Mathematics examination.
A uniform ladder 6 m long and weighing 180 N rests against a smooth vertical wall and a rough horizontal floor. The coefficient of static friction between the ladder and the floor is \(\mu\). The ladder makes an angle \(\theta\) with the floor and is on the verge of slipping. (a) Derive an expression for \(\mu\) in terms of \(\theta\). (b) If \(\mu = 0.30\), calculate the minimum angle \(\theta_{\min}\) (in degrees) for which the ladder will not slip.
