A2.44 gram penny is on a turn table. it starts from rest at a radius of 0.136 meters and the turn table speeds up until the penny flies off with a tangential speed of 0.574 m/s. a. what coefficient of static friction exists between the penny and turntable if the penny doesn't fly off until it reaches this speed? b. suppose a 5.7-gram quarter has the same coefficient of static friction between it and the turntable as does the penny? in what way will the speed at which it les off differ from that of the penny?
