A 10 kg wheel with a moment of inertia of 0.162 kg. m² about its center is released from rest on an inclined plane at 60°. Originally, the coefficient of kinetic friction is μ=0.30, causing the wheel to slip. Find the minimum coefficient of friction necessary for the wheel not to slip. 200 mm 60° -0.30
