A machine gun fires `25g` bullet at the rate of 600 bullets per minutes with a speed of `200m//s`. Calculate the force required to keep the gun in position.

Explanation

To calculate the force required to keep the machine gun in position while firing bullets, we can use the principle of momentum and Newton's second law of motion. Here’s a step-by-step solution:

### Step 1: Convert the mass of the bullet to kilograms
The mass of one bullet is given as 25 grams. We need to convert this to kilograms because the standard unit of mass in physics is kilograms.

\[ \text{Mass of bullet} = 25 \, \text{g} = \frac{25}{1000} \, \text{kg} = 0.025 \, \text{kg} \]
