Question

Why the displacement along y axis is zero in projectile motion along inclined plane?

Answer 1

ANSWER :

The horizontal velocity of a projectile isconstant (a never changing in value), There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a projectile is independent of its vertical motion.
