A projectile is launched at an angle of 30 to the horizontal with a speed of 30 m/s.
How does the horizontal component of its velocity 1.0 s after launch compare with its horizontal component of velocity 2.0 s after launch?

There are no horizontal forces here! NONE!!! Nada ! Zilch !
THEREFORE there is no horizontal acceleration !
Therefore there is no rate of change of horizontal velocity component !
Therefore the answer to this silly trick question is that there is no change in the horizontal velocity until the projectile hits something.
