In order to determine the coefficients of friction between rubber and various surfaces, a student uses a rubber eraser and an inclined board. In one experiment, the eraser slips down the incline when the angle of inclination is 17.3 degrees, and then moves down the incline with a constant speed when the angle is reduced to 12.1 degrees. (a) Determine the coefficient of static friction for this experiment. mu = (b) Determine the coefficient of kinetic friction for this experiment. mu = Thanks so much! I really appreciate it!!!
