A cart loaded with bricks has a total mass of 18 kilogram and is pulled at constant speed by a rope. The rope is inclined at 24.6 degree above the horizontal and the cart moves 29.5 meter on a horizontal floor. The coefficient of kinetic friction between cart and ground is 0.4. The acceleration of gravity is 9.8m/s2 .
Find how much work is done on the cart by the rope?
