Question: A cart loaded with bricks has a total mass of 7.5 kg and is pulled at constant speed by a rope. The rope is inclined at 21.4 above the horizontal and the cart moves 25.3 m on a horizontal floor. The coefficient of kinetic friction between ground and cart is 0.7. The acceleration of gravity is 9.8 m/s2.
Part A: How much work is done on the cart by the rope?
Answer in units of kJ
I want help to find how much work is done on the cart by the rope.
