A `50 kg` woman is on a large swing (generally seen in fairs) of radius 9 m that rotates in a vertical circle at `6 "reve"//min`. What is the magnitude of her weight when she has moved halfway up ?

A 70 kg man stands in contact against the ineer wall of a hollow cylindrical drum of radius 3 m rotating about its vertical axis with 200 rev//min . The coeffcient of friction between the wall and his clothing is 0.15. What is the minimum rotational speed of the cylinder to enable the man of remain stuck to the wall ( without falling) when the floor ids suddenly removed?
