. The drum of a laundry machine, which can be modeled as a cylinder with a radius of 32 cm, is spinning about its vertical axis with an unknown angular speed ω. A wallet in contact with the inside wall of the spinning drum moves with the drum without slipping. The coeficient of static friction between the wallet and the surface of the drum is µs=0.45. The mass of the wallet is 210 grams. What is the minimum value the angular speed can have (ω min) so that the wallet does not slip ?

A little mouse of mass m=.1kg got into a dryer which has a cylinder with radius r=25cm rotating horizontally. When the dryer was turned on it archived angular speed of 125 revolutions per minute, it was found that the mouse stuck to the vertical wall of the drum. What is the minimum coefficient of static friction that prevents the mouse from falling on the bottom of the dryer?

1. Three children are riding on the edge of a merry‑go‑round that has a mass of 105 kg and a radius of 1.80 m. The merry‑go‑round is spinning at 22.0 rpm. The children have masses of 22.0, 28.0, and 33.0 kg. If the 28.0 kg child moves to the center of the merry‑go‑round, what is the new angular velocity in revolutions per minute? Ignore friction, and assume that the merry‑go‑round can be treated as a solid disk and the children...
