Question

Choose the true statement about a firearm's maximum projectile range.

A. It increases with a higher initial velocity
B. It decreases with a higher angle of elevation
C. It is unaffected by air resistance
D. It depends only on the caliber of the firearm

Answer 1

The true statement about a firearm's maximum projectile range is that it increases with a higher initial velocity, and factors such as the initial angle and air resistance also play crucial roles.

Step-by-step explanation:

The true statement about a firearm's maximum projectile range is that it increases with a higher initial velocity. The initial velocity of a projectile greatly affects its range; the greater the initial speed (v0), the greater the range will be. The optimal initial angle for maximum range is 45° in the absence of air resistance, but with air resistance, it would be slightly smaller, around 38°. Additionally, it is incorrect to say that the range decreases with a higher angle of elevation; the range increases up to 45° and then decreases past that angle. Air resistance has a significant effect on projectile motion, decreasing time of flight and the range. It is also not accurate to say the maximum range depends only on the caliber, as it is also dependent on the muzzle velocity and other factors.
