A bоx оf mаss m = 10.0 kg mоving аt 0.500 m/s is pushed by а force F = {F} N across a horizontal floor. The applied force is directed at an angle θ = 60.0⁰ as shown in the drawing. The coefficients of static and kinetic friction between the box and the floor are μs=0.400 and μk=0.300, respectively. This produces a maximum static friction of 81.6 N and kinetic friction of 61.2 N. What is the work done (in Joules) by the frictional force after the box moved a distance of d = 10.0 m?
