A high-powered 7-mm Remington magnum rifle fires a bullet with a velocity of 900 m/s on a rifle range. Neglecting air resistance:

(a) Calculate the distance at which the bullet will drop when fired horizontally at a range of 200 m.

(b) To compensate for the bullet drop, the telescope sight is pointed directly at the target, and the gun barrel is aligned to be slanted slightly upward. The bullet strikes the target as desired.

- Suppose the rifle is fired uphill at a target 200 m away with an upward slope of 45°. Should you aim above or below the target, and by how much?

- What should you do when shooting on a downhill slope at a 45° angle below horizontal?

Answer :

Final answer:

When a 7-mm Remington magnum rifle fires a bullet with a velocity of 900 m/s, it will fall a certain distance due to gravity. This distance can be calculated using time from the horizontal motion equation and height from the motion-under-gravity equation. When shooting at an uphill or downhill target, adjustment should be made based on the slope and gravity's effect.

Explanation:

The subject of this question is Projectile Motion which is a part of Physics. Considering the effects of gravity is vital when determining how a bullet will travel.

(a) When neglecting air resistance, the distance a bullet will drop when fired horizontally can be calculated using the equation for the motion under gravity, which is h = 0.5*g*t^2. In our case, we know the gravity (g) is approximately 9.81 m/s² and time (t) can be found by using the equation for horizontal motion without air resistance, d/v = t. Here, distance (d) is 200 m and velocity (v) is 900 m/s. Once we have calculated time, we can substitute these values into our first equation to calculate the distance the bullet will drop.

(b) With an upward slope of 45°, if you aim directly at the target, the bullet will strike above the target due to the combined effect of the bullet's initial upward trajectory and the slope. Therefore, you should aim below the target. If you are shooting downhill at a 45° angle, you should aim above the target because the bullet will drop due to gravity.
