A cannonball of mass 500 g is fired with a speed of 15 m`s^(-1)` . Find : (i) its kinetic energy, and (ii) momentum

Explanation

To solve the problem, we need to find the kinetic energy and momentum of a cannonball with a given mass and speed. Let's break it down step by step.

### Given:
- Mass of the cannonball (m) = 500 g
- Speed of the cannonball (v) = 15 m/s

### Step 1: Convert mass from grams to kilograms
Since the standard unit of mass in physics is kilograms (kg), we need to convert the mass from grams to kilograms.
