The wheelbarrow and its contents have a mass of 40 kg and a mass center at G, excluding the wheel. The wheel has a mass of 4 kg and a radius of gyration k0 = 0.120 m. If the wheelbarrow is released from rest from the position shown, determine its speed after it travels 4 m down the incline. The coefficient of kinetic friction between the incline and A is A = 0.3. The wheels roll without slipping at B.
