Angular Impulse

Photon is quantum of radiation with energy E= hv where v is frequency and h is Planck's constant . The dimesions of h are the same as that of A) Linear impulse B) Angular impulse C) Linear momentum D) Angular momentum

A cylinder having moment of inertia, which is free to rotate about its axis, receives an angular impulse of J kgm^(2)//s initially, followed by similar impulse after every 4 s . What is the angular speed of the cylinder 30 s after the initial impulse?

A solid sphere (initially at rest) of mass 7 kg and radius 40 cm which is free to rotate about its axis is given an angular impulse of 5kgm^(2)s^(-1) followed by the similar impulse after every 5 second. Calculate the angular speed of sphere 50 s after the initial impulse.

A wheel of mass 2 kg and radius 20 cm initially at rest is free to rotate about its axis. It receives an angular impulse of 4kgm^(2)s^(-1) initially and similar impulse after every 5 s of initial one. Calculate the angular speed of the wheel 22 s after the initial impulse.

A cylinder having moment of inertia, which is free to rotate about its axis, receives an angular impulse of J kgm^(2)//s initially, followed by similar impulse after every 4 s . What is the angular speed of the cylinder 30 s after the initial impulse?
