# Aworker drags a box of mass 50 kg across a horizontal floor. the worker attaches a rope to the box and pulls on the rope so that the rope makes a constant angle of 36.8 o 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. find anâ€ expressionâ€ for the magnitude of the pulling force that the worker exerts on the rope.

b. find aâ€ numericalâ€ valueâ€ for the magnitude of the pulling force that the worker exerts on the rope. express your answer as a percentage of the magnitude of the gravitational force acting on the box.
