The angle at which a projectile must be fired to cover maximum range is
Answer Details
The angle at which a projectile must be fired to cover maximum range is 45 degrees.
When an object is thrown or fired, it follows a curved path known as a projectile motion. The path of the projectile is affected by gravity and air resistance. To achieve maximum range, the projectile must be launched at an angle that balances the effects of gravity and air resistance.
If the projectile is launched at a very low angle (close to 0 degrees), it will not travel very far because gravity will pull it down quickly. On the other hand, if it is launched at a very high angle (close to 90 degrees), it will not travel very far because most of its initial velocity will be directed upwards against gravity.
At 45 degrees, the projectile's initial velocity is divided equally into its horizontal and vertical components. The horizontal component of velocity keeps the projectile moving forward while the vertical component of velocity is affected by gravity, causing the projectile to rise and fall. This balance between horizontal and vertical velocities allows the projectile to cover the maximum distance before hitting the ground.
Therefore, firing a projectile at 45 degrees will give it the maximum range.
