A cart loaded with bricks has a total mass of 13.8 kg and is pulled at constant speed by a rope. The rope is inclined at 30.6 above. the horizontal and the cart moves 15.9 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/s. What is the normal force exerted on the cart by the floor? Answer in units of N. 015 (part 2 of 3) 10.0 points How much work is done on the cart by the rope? Answer in units of kJ. 016 (part 3 of 3) 10.0 points Note: The energy change due to friction is a loss of energy. What is the energy change W, due to fric- tion? Answer in units of kJ.
