A ball of mass 05 kg slows down from a speed of 5 m `s^(-1)` to that of 3 m `s^(-1)` . Calculate the change in the kinetic energy of the ball.

Explanation

To solve the problem of calculating the change in kinetic energy of a ball with a mass of 5 kg that slows down from a speed of 5 m/s to 3 m/s, we can follow these steps:

### Step 1: Understand the formula for kinetic energy
The formula for kinetic energy (KE) is given by:
\[ KE = \frac{1}{2} m v^2 \]
where \( m \) is the mass of the object and \( v \) is its velocity.
