# A cart loaded with bricks has a total mass of 13.4 kg and is pulled at constant speed by a rope. The rope is inclined at 21.1° above the horizontal and the cart moves 17.2 m on a horizontal floor. The coefficient of kinetic friction between ground and cart is 0.3. The acceleration of gravity is 9.8 m/s2. What is the normal force exerted on the cart by the floor? Answer in units of N.
