Question

Assuming no air friction and ay = -g, the horizontal displacement of a projectile depends on what?

a) Initial vertical velocity
b) Initial horizontal velocity
c) Initial vertical height
d) Initial angle of projection

Answer 1

The horizontal displacement of a projectile depends on the initial horizontal velocity and the initial angle of projection.

Step-by-step explanation:

The horizontal displacement of a projectile depends on the initial horizontal velocity and the initial angle of projection.

When a projectile is launched, it travels in both the horizontal and vertical directions. The initial horizontal velocity determines how far the projectile will travel in the horizontal direction. The initial angle of projection determines the vertical component of the projectile's velocity, which affects the time of flight and therefore the horizontal displacement.
