The momentum of a body is doubled. By what percentage does its kinetic energy increase ?

Explanation

To solve the problem of how the kinetic energy changes when the momentum of a body is doubled, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the relationship between momentum and kinetic energy**:
The kinetic energy (K) of a body is related to its momentum (p) and mass (m) by the formula:
\[
K = \frac{p^2}{2m}
