Please Help: The launching velocity of a projectile is 20m/s at 53 degrees above the horizontal. what is the vertical component of its velocity at launch? Neglecting air friction, which of these components remains constant throughout the flight path? which of these components determines the projectile's time in the air?

I would guess that the acceleration would remain constant. To tell you the truth, I kind of don't remember much about these questions. I hope I'm not wrong, but I think that either angle or mass have something to do with "Air Time". I hope this helps.

I really wish that I could help you more, but I am somewhat useless in this subject. Sorry... :\

It's fine

The horizontal component of the velocity remains constant since there is no acceleration horizontally to change its value.  The vertical component of velocity dictates time because this component is affected by gravity at a rate of 9.8 [m/s] per 1 [s].
