Two horses pull a large crate at fix speed across a barn floor by means of two light steel cables. A large box of mass 250 kilogram sits on the crate. As the horse pull, the cables are parallel to the horizontal floor. The coefficient of friction between the barn floor and the crate is 0.25.
a) Calculate the work done by each horse if the box is moved a distance of 25 meter?
b) Find the tension in each cable if the angle between each cable and the direction the crate moves is 15 degree?
