Homework Statement


A cart loaded with books has a total mass of 20kg and is pulled at a constant speed by a rope inclined at 30 degrees above the horizontal. The cart moves a distance of 10m on a horizontal surface. The coefficient of kinetic friction between the cart and the surface is 0.45. Find the tension in the rope.

Try drawing all the components of the forces.
 
I have I need a step by step breakdown.
 
Post a picture of your attempt. Even an MS Paint jpeg would do.
