Find the ratio of the distances travelled by a freely falling body in first, second and third second of its fall.

Explanation

To find the ratio of the distances travelled by a freely falling body in the first, second, and third seconds of its fall, we can follow these steps:

### Step 1: Understand the motion of the freely falling body
A freely falling body is under the influence of gravity alone. The distance travelled in a given time can be calculated using the formula:
\[ s = ut + \frac{1}{2}gt^2 \]
where:
- \( s \) is the distance travelled,
- \( u \) is the initial velocity (which is 0 for a freely falling body),
