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(=2sqrt(2)m) .The string is pulled vertically upward to prevent the centre of mass from falling as the cylinder unwinds the string.Find the length of the string unwound when the cylinder has reached a speed omega(=5 rad/s ) . (g=10m/s^(2))

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 is warapped around a cylinder of mass m and radius r. The string is also connected to a block of same mass m with the help of another pulley as shown in figure. The angular acceleration of the cylinder is ( friction is sufficient for rolling ) ( all pulleys are ideal)

A string is wrapped several time on a cylinder of mass M and radius R , the cylinder is pivoted about its axis of symmetery . A block mass of m tied to the string rests on support so that the string is black. The block is lifted upto a height h and the support is removed. (shown in figure) When the string experience a jerk, a large impulsive force is generated for a short duration, so that contribution of weight mg can be neglected suring this duration. then what will be speed of blocks m , just after string has becomes taut

A string is wound around a hollow cylinder of mass 5 Kg and radius 0.5 m. If the string is now pulled with a horizontal force of 40 N, the cylinder is rolling without slipping on a horizontal surface (see figure), then the angular acceleration of the cylinder will be (Neglect the mass and thickness of the string).
