Problem
A 70 kg man stands in contact with the inner wall of a hollow cylindrical drum of radius 3 m 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 that enables the man to remain stuck to the wall without falling when the floor is suddenly removed?
