Question

Name the unit of physical quantity obtained by the formula $\frac{2K}{V^2}$. Where K: kinetic energy, V: Linear velocity.

Answer 1

Kinetic energy of the body is defined as $K=\frac{1}{2}M{V}^2$
where $M$ is the mass of the body.
$⟹$ $\frac{2K}{V^2}=M$
Thus $\frac{2K}{V^2}$ represents the mass of the body.

Unit of Mass is given by Kg
