A body of moment of inertia of 3 kg m^(2...

A body of moment of inertia of `3 kg m^(2)` rotating with an angular velocity of 2 rad/s has the same kinetic energy as that that of mass 12 kg moving with a velocity of

A

`8` m/s

B

`0.5` m/s

C

`2` m/s

D

`1` m/s

Text Solution

Verified by Experts

The correct Answer is:
D
`(1)/(2)I omega^(2)=(1)/(2)mv^(2)implies(1)/(2)xx3xx4=(1)/(2)xx12xxv^(2)`
implies `v=1` m/s
