**48. In an automatic clothes dryer, a hollow cylinder moves the clothes on a vertical circle (radius r = 0.32 m), as the drawing shows. The appliance is designed so that the clothes tumble gently as they dry. This means that when a piece of clothing reaches an angle of 0 above the horizontal, it loses contact with the wall of the cylinder and falls onto the clothes below. How many revolutions per second should the cylinder make in order that the clothes lose contact with the wall when 0 = 70.0°?

Question
**48. In an automatic clothes dryer, a hollow
cylinder moves the clothes on a vertical circle
(radius r = 0.32 m), as the drawing shows.
The appliance is designed so that the clothes
tumble gently as they dry. This means that
when a piece of clothing reaches an angle
of 0 above the horizontal, it loses contact
with the wall of the cylinder and falls onto
the clothes below. How many revolutions per
second should the cylinder make in order that the clothes lose contact
with the wall when 0 = 70.0°?
