Question

6. A body of moment of inertia 3kg.m2 otating with an
angular velocity 2 rad/s has the same kinetic energy as a
mass of 12 kg moving with a velocity of
(1m/s, 2m/s, 4m/s, 8m/s)​

Answer 1

Answer:

A body of moment of inertia of 3kgm2 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. ∴ v2=1 v=1m/s.
