CAIE A-Level Mathematics A2 4.1.1 Forces Questions question 1

[Maximum number: 1]

A block of mass 8 kg slides down a rough plane inclined at 30∘30^{\circ} to the horizontal, starting from rest. The coefficient of friction between the block and the plane is μ\mu. The block accelerates uniformly down the plane at 2.4 m s−22.4 \mathrm{~m} \mathrm{~s}^{-2}.

Draw a diagram showing the forces acting on the block.
