You place a penny on a turntable at a distance of 14.3 cm from the center. the coefficient of static friction between the penny and the turntable is 0.400. the turntable's angular acceleration is 2.45 rad/s². how long after you turn on the turntable will the penny begin to slide off of the turntable? [note: assume the tangential component of friction is sufficiently small and can be ignored.]
