Question 3
A wooden crate of mass \(8.5\) kg rests on an inclined plane that makes an angle of \(25°\) with the horizontal. A horizontal force of magnitude \(35\) N is applied to the crate, as shown in the diagram. The coefficient of kinetic friction between the crate and the plane is \(0.18\). The crate moves up the incline. Determine the magnitude of the net force acting on the crate. Show your working.
