A force is applied on a body of mass 20 kg moving with a velocity of `40ms^(-1)`. The body attains a velocity of `50ms^(-1)` in 2 second. Calculate the work done by the body.

Explanation

To solve the problem, we need to calculate the work done by the body when a force is applied. Here's a step-by-step solution:

### Step 1: Identify the given values
- Mass of the body (m) = 20 kg
- Initial velocity (u) = 40 m/s
- Final velocity (v) = 50 m/s
- Time (t) = 2 seconds
