Question 9

A sledge of mass 15 kg is at rest on a rough horizontal patch of ice. The coefficient of friction between the sledge and the ice is 0.2. A child pulls the sledge with a force of F F\,F N at an angle of 30∘ 30^\circ\,30∘ to the horizontal. The sledge is on the point of sliding.

Find the value of FFF.
