Answer : acceleration , a = g = 9.8 [tex]m/s^2[/tex]

Explanation :

Projectile motion is the motion of an object projected into the air, that is subjected to only acceleration due to gravity.

When a projectile is fired, the velocity have two components i.e. x and y. The x- component of acceleration is zero because the speed is constant. But in y- direction,  the acceleration is constant i.e. g or 9.8 m/s^2.
