Question

which of the following statements about a projectiles motion is always true? the projectiles speed is constant. the vertical and horizontal motions are independent. the acceleration of the projectile is always zero. the projectiles horizontal velocity is always zero.

Explanation:

In projectile motion, the vertical motion is affected by gravity while the horizontal motion has a constant - velocity (assuming no air - resistance). The two components are independent of each other. The speed is not constant as the vertical velocity changes due to gravity, the acceleration is not zero (there is a constant vertical acceleration of \(g\) near the Earth's surface), and the horizontal velocity is non - zero if there is an initial horizontal velocity.

Answer:

The vertical and horizontal motions are independent.
