Which answer is true about an object undergoing projectile motion? a
b
Oc

ax = ay = -8
VX = constant, and ay = -g
VX = constant, and vy = constant
ax = constant, and vy = constant

Select the answer that states:

VX = constant, and ay = -g

Explanation:

In the case of an object undergoing projectile motion, such motion is divided in two analysis. The vertical analysis uses kinematic equations associated with an accelerated motion under the constant acceleration of gravity, and the horizontal analysis is that of a uniform motion at constant velocity.

Therefore the projectile motion uses the velocity in the horizontal (x-direction) as constant. and the vertical motion (associated with the y-axis) a motion with acceleration equal to "g".

Then, the corect answer is the one that states:

"VX = constant, and ay = -g"
