Using second law of motion, derive the relation between force and acceleration. A bullet of `10g` strikes a sand-bag at a speed of `10^(3)ms^(-1)` and gets embedded after travelling `5cm`.Calculate
(i) the resistive force exerted by the sand on the bullet (ii) the time taken by the bullet to come to rest.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Derive the relation between force and acceleration using Newton's Second Law of Motion.

According to Newton's Second Law of Motion:
\[ F = m \cdot a \]
where:
- \( F \) is the force applied,
...
