3. A bug is 12 cm from the center of a turntable m/ that is rotating with a frequency of 45 rev/min. What minimum coefficient of friction is required V:0.51 28 so that the bug stays on the turntable?

A bug on a turntable will have greater tangential speed if it is located near the edge of the rotation object. O True O False

Lx Gi A 325-kg merry-go-round with a radius of 1.50 m is spinning counterclockwise, as viewed from above, at 4.80 rad/s. A 35.0-kg child is hanging on tightly 1.25 m from the rotation axis. Her father applies friction to the outer rim to slow the merry-go-round to a stop in 5 s. Model the merry-go-round as a solid disk, and define counterclockwise as the positive direction of rotation. How much torque t must the child's father apply? 432 T = N-m Incorrect
