# If Rotational Kinetic Energy Is 50% Of Total Kinetic Energy Then The Body Will Be

Sol:

As given:

Rotational Kinetic Energy = Translational Kinetic Energy

$$\Rightarrow \frac{1}{2} I\omega ^{2} = \frac{1}{2} mv ^{2}$$

As v =$$\omega r$$ $$\Rightarrow I * \omega ^{2} = m * \omega ^{2}r^{2}\\\Rightarrow I = mr^{2}$$

Therefore, if rotational kinetic energy is 50% of total kinetic energy, then the body will be a ring.
