Rosa has designed a pulley system for a school science project. She has determined that as the coefficient of friction increases, the efficiency of the pulley decreases. With a coefficient of friction of 0.2, the efficiency of the pulley is 60%. What would you expect the efficiency to be if the coefficient of friction increased to 0.3?
