AI Generated Solution

To solve the problem, we need to determine the force required to keep the machine gun in position while it fires bullets. This force is essentially the recoil force due to the bullets being fired. ### Step-by-Step Solution: 1. **Identify the mass of the bullet and convert it to kilograms:** - The mass of one bullet is given as 35 grams. - To convert grams to kilograms: \[ ...
