At the beginning of a new school term, a student moves a box of books by attaching a rope to the box and pulling with a force of F = 85.7 N at an angle of 59°, as shown in the figure. The acceleration of gravity is 9.8 m/s2. The box of books has a mass of 13 kg and the coefficient of kinetic friction between the bottom of the box and the floor is 0.45. What is the acceleration of the box?
