A 58 kg runner is standing on the outer edge of a horizontal turntable mounted on a frictionless axis through its center. The turntable has a radius of 2.9 m and moment of inertia 500.0 kg.m2 and is currently at rest. The runner starts his run along the outer edge and is observed to run with a speed, relative to the earth, of 5.6 m/s. If he runs for 60 sec, how many revolutions does the turntable make?
