$\"\"$

Mass of the particle with speed $\"\"$ is $\"\"$ .

Find the inverse function by solving the above equation for $\"\"$ since $\"\"$ .

Consider

$\"\"$ .

Multiply on each side by $\"\"$ .

$\"\"$

Apply square on each side.

$\"\"$

Therefore, inverse of the function $\"\"$ .

Here the inverse function represents the speed of the particle.
