A wooden crate of mass 30 kg is at rest on a rough horizontal warehouse floor. The coefficient of friction between the crate and the floor is 0.35. A rope is used to pull the crate with a force of F F\,F N at an angle of 25∘ 25^\circ\,25∘ to the horizontal. The crate is on the point of sliding.
Find the value of FFF.
