A light mass and a heavy mass have equal momentum. Which will have more kinetic energy?
[Hint : kinetic energy K = `p^(2)//2m` where p is the momentum)

Explanation

To solve the problem of which mass (light or heavy) has more kinetic energy when both have equal momentum, we can use the formula for kinetic energy in terms of momentum.

### Step-by-Step Solution:

1. **Understand the relationship between kinetic energy and momentum**:
The kinetic energy (K) of an object can be expressed in terms of its momentum (p) and mass (m) using the formula:
\[
K = \frac{p^2}{2m}
