1. the horizontal and vertical components of a projectile's velocity are
a. directly proportional
c. independent of each other
b. inversely proportional d. equal

The horizontal and vertical components of a projectile's velocity are independent of each other.

Option C

Explanation:

The path of a projectile is determined by two components of motion. They are termed as horizontal and the vertical components. Since both components velocity are perpendicular to each other, so it can stated that they are independent of each other.

Even it can seen that when the horizontal components of velocity is constant, then there will be change in the vertical components of velocity leading to free fall projectile path.

And in the absence of gravity, there will be change in the horizontal components of velocity with zero vertical component of velocity. Thus, the horizontal and the vertical components of a projectile’s velocity are seemed to be independent of each other.
