- To determine the coefficients of friction between rubber and various surfaces, a student uses a rubber eraser and an incline. In one experiment, the eraser begins to slip down the incline when the angle of inclination is 36.0 and then moves down the incline with constant speed when the angle is reduced to 30.0. From these data, determine the coefficients of static and kinetic friction for this experiment.5. A barge is pulled by two tugboats. If the resultant of the forces exerted by the tugboats is 5000 lb directed along the axis of the barge, determine the tension in each of the ropes for a= 65° B 30° CA.
