A string is wrapped around a cylinder of mass M and radius r. The string is pulled vertically upward to prevent the center of mass from falling as the cylinder unwinds the string. (a) What is the tension in the string? B) How much work has been done on the cylinder once it has reached an angular speed omega ? c) what is the length of string unwound in the time its acquires angular speed omega ?

A string is wrapped around a cylinder of mass M and radius R. The string is pulled vertically upward to prevent the centre of mass from falling as the string unwinds. Assume that the cylinder remains horizontal throughout and the thread does not slip. Find the length of the string unwound when the cylinder has reached an angular speed omega .

A string of negligible mass is wrapped on a cylindrical pulley of mass M and radius R. The other end of string is tied to a bucket of mass m. If the pulley rotates about a horizontal axis then the tension in the string is :

A string wrapped around a cyliner of mass m and radius R . The end of the string is connected to block of same mass hanging vertically. No friction exists between the horizontal surface and cylinder. Velocity of point of contact 'of cylinder at this moment is:
