The kinetic energy of an object is K. If its velocity is doubled, then its kinetic energy will becomes nk. What is the value of n ?

Explanation

To solve the problem, we need to determine how the kinetic energy of an object changes when its velocity is doubled.

### Step-by-Step Solution:

1. **Understand the formula for kinetic energy (KE)**:
The formula for kinetic energy (K) is given by:
\[
K = \frac{1}{2} m v^2
