Two bodies of equal masses are moving with uniform velocities v and 2v. Find the ratio of their kinetic energies

Explanation

To find the ratio of the kinetic energies of two bodies with equal masses moving with velocities \( v \) and \( 2v \), we can follow these steps:

### Step 1: Write the formula for kinetic energy
The kinetic energy (KE) of an object is given by the formula:
\[ KE = \frac{1}{2} m v^2 \]
where \( m \) is the mass of the object and \( v \) is its velocity.
