A machine gun has a mass of `20 kg` . It fires` 35 g` bullets at the rate of` 400` bullets per minute with a speed of `400 m//s` What force must be applied to the gun to keep it in position ?

Explanation

To solve the problem of how much force must be applied to the machine gun to keep it in position while firing bullets, we can follow these steps:

### Step 1: Understand the problem
The machine gun has a mass of \(20 \, \text{kg}\) and fires bullets of mass \(35 \, \text{g}\) at a speed of \(400 \, \text{m/s}\). It fires \(400\) bullets per minute. We need to find the force required to keep the gun stationary.

### Step 2: Convert bullet mass to kilograms
The mass of each bullet in kilograms is:
