A moving body weighing 400 N possesses 500 J of kinetic energy. Calculate the velocity with which the body is moving. `(g=10ms^(-2))`

Explanation

To solve the problem step by step, we will follow these calculations:

### Step 1: Calculate the mass of the body
We know that weight (W) is given by the formula:
\[ W = m \cdot g \]
Where:
- \( W \) = weight of the body (400 N)
- \( m \) = mass of the body (in kg)
