Answer 1

hey mate your answer is here

The horizontal velocity of a projectile is constant ,There is a vertical acceleration caused by gravity; its value is 9.8m/s/s ,down, the vertical of a projectile changes bu 9.8m/s each second ,the horizontal motion of a projectile is independent of its vertical motion

i hope this helpfull answer to you dear

hayy mate here is your answer

There are no horizontal forces acting upon projectiles and thus no horizontal acceleration, ... 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.
