Calculate the kinetic energy acquired by a body of mass 5 kg initially at rest , when subjected to a force of 20 N , at the end of 8 s .

Explanation

To calculate the kinetic energy acquired by a body of mass 5 kg when subjected to a force of 20 N for 8 seconds, we can follow these steps:

### Step 1: Calculate the acceleration of the body
Using Newton's second law of motion, we can calculate the acceleration (a) of the body using the formula:

\[ a = \frac{F}{m} \]
