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 an†expression†for the magnitude of the pulling force that the worker exerts on the rope.
b. find a†numerical†value†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.
