Final answer:
The maximum effective range of the M-203 grenade launcher on a point target is 150 meters, which demonstrates practical use of projectile motion concepts such as the optimum angle of launch, air resistance, and the effects of gravity.
Step-by-step explanation:
The maximum effective range of the M-203 grenade launcher on a point target is 150 meters. This question relates to understanding the application of projectile motion principles and the effects of gravity on the trajectory of a launched object, such as a grenade from a launcher. When discussing the range of a projectile, it's important to consider the optimum angle of launch, which for maximum distance on level ground is 45°. This is based on physics principles that dictate that a projectile launched at 45° in a vacuum without air resistance will cover the maximum horizontal distance. However, in practice, air resistance, launch speed, and the height at which the launcher is fired can affect the range. The question on the maximum effective range of the M203 grenade launcher is a practical application of these principles.
