A teacher place a 75-pound box of stationery on a ramp having an angle of inclination 60 degree to the horizontal and pulls the box up the ramp using a wire harness attached to the end by exerting a force of 80 pounds at an angle of zero degree to the ramp. What is the force of friction restricting the movement of a box if the teacher pulls it up the ramp at a constant speed? Please explain your answer step by step and draw a graph on a single cartesian plane in your note. *
