A body having a moment of inertia about its axis of rotation equal to `3 kg-m^2` is rotating with angular velocity of `3 rad s^(-1)`. Kinetic energy of this rotating body is same as that of a body of mass 27 kg moving with a velocity `v`. The value of `v` is
Options:
(a) `1ms^(-1)`
(b) `0.5 ms^(-1)`
(c) `2 ms^(-1)`
(d) `1.5 ms^(-1)`
