For how long should a force of `100 N` act on a body of mass `20kg` so that it aquires a velocity of `100m//s`?

Explanation

To solve the problem, we need to determine how long a force of 100 N should act on a body of mass 20 kg to achieve a velocity of 100 m/s. We will use Newton's second law of motion and the equations of motion.

### Step-by-Step Solution:

1. **Identify the Given Values**:
- Force (F) = 100 N
- Mass (m) = 20 kg
- Final velocity (v) = 100 m/s
