Question

A cylinder of mass 5 kg. and radius 30 cm, and free to rotate about its axis, receives an angular impulse of 3 kgM² S^-1initially followed by a similar impulse after every 4sec. what is the angular speed of the cylinder 30 sec after initial emulse ? The cylinder is at rest initially

$106, 7 {radS}^{- 1}$
$206, 7 {radS}^{- 1}$
$107, 6 {radS}^{- 1}$
$207, 6 {radS}^{- 1}$

The correct answer is: $106 comma 7 radS to the power of negative 1 end exponent$
