Question

In projectile motion why y component of final velocity is zero?​

Answer 1

Answer:

i know that in some cases the initial and final velocity do equal each other. However, I am confused as to when that applies, in what cases. It seems logical that the initial velocity and final velocity only equal when the projectile is parabolic and symmetric (where y = yo). I have nothing to support this.

One case I am concerned about is when the initial height is not equal to the landing height (Yo does not equal Y), and the projectile is shot at an angle theta.

hope it will help
