A person stands in contact against the inner wall of a rotor of radius r. The coefficient of friction between the wall and the clothing is `mu` and the rotor is rotating about vertical axis. The minimum angular speed of the rotor so that the person does not slip downward is

A 70kg man stands in contact against the inner wall of a hollow cylindrical drum of radius 3m rotating about its vertical axis. The coefficient of friction between the wall and his clothing is 0.15 . What is the minimum rotational speed of the cylinder to enable the man to remain stuck to the wall (without falling) when the floor is suddenly removed?

A block of mass 10 kg in contact against the inner wall of a hollow cylindrical drum of radius 1m. The coefficient of friction between the block and the inner wall of the cylinder is 0.1. The minimum angular velocity needed for the cylinder to keep the block stationary when the cylinder is vertical and rotating about its axis, will be (g=10 m//s^(2))
