A worker exerts a pulling force on a box. The worker exerts this force by attaching a rope to the box and pulling on the rope so that the rope makes a constant angle of 36.8° above the horizontal. The coefficient of kinetic friction between the box and the floor is 0.10. It takes the worker 5.12 seconds to move the box 10 m from rest. A. What is the magnitude of the pulling force that the worker exerts on the box? Express your answer as a percentage of the magnitude of the gravitational force acting on the box. Indicate any assumptions that you made.
