Question

Doc Samson needs to move a box of machinery with a mass of 2,00 times 10^3[kg]. He attaches a steel cable and pulls the box across a horizontal floor so the cable makes an angle of 30.0 degree relative to the ground. There is friction between the box and the floor such that, mu_k = 0.100. If his applied force is 1.50 times 10^4 [N] and he drags the box for 10.0[m], how much total work is performed on the box during this motion?
