A cylinder of mass 5kg and radius 30cm, ...

A cylinder of mass 5kg and radius 30cm, and free to rotate about its axis, receives an angular impulse of 3kg `m^(2)s^(-1)` initially followed by a similar impulse after every 4s. What is the angular speed of the cylinder 30s after the initial impulse? The cylinder is at rest initially.
