A rocket is moving up with a velocity `upsilon` if the velocity of this rocket is suddenly tripled, what will be the ratio of two kinetic energies ?

Explanation

To solve the problem of finding the ratio of the kinetic energies of a rocket moving with an initial velocity \( v \) and then tripled to \( 3v \), we will follow these steps:

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