A force of `4N` acts on a body of mass `2kg` for `4s`. Assuming the body to be initially at rest, find (a) its velocity when the force stops acting (b) the distance covered in `10s` after the force starts acting.

Explanation

To solve the problem step by step, we will break it down into two parts as given in the question.

### Part (a): Finding the velocity when the force stops acting

1. **Identify the given values**:
- Force (F) = 4 N
- Mass (m) = 2 kg
- Time (t) = 4 s
