A cart loaded with bricks has a total mass of 12.3 kg and is pulled at constant speed by a rope. The rope is inclined at 24.5 degrees above the horizontal and the cart moves 12.5 m on a horizontal surface. The coefficient of kinetic friction between ground and
cart is 0.503.
The acceleration of gravity is 9.8 m/ s^2 :
How much work is done on the cart by the rope? Answer in units of J.
