Zero.
The horizontal acceleration i.e. Vx throughout the trajectory remains constant only of the air resistance is neglected. The gravity can affect the y-component of velocity but is unable to affect its x-component. Acceleration (delta V) does not occur unless a change comes into play per Newton. Gravity does not effect x but air resistance would. Likewise, projectiles launched from e.g. an explosion experience a reducing delta V in that acceleration from an explosion is subject to the inverse square rule.
Neglecting air resistance, the components of acceleration of an object that's dropped, tossed, pitched, flung, lobbed, heaved, launched, or shot are constant. The horizontal component is zero. The vertical component is 9.8 meters per second2, directed downward. These are both constant throughout the object's trajectory.
A vector with magnitude = 70 , directed 20° above or below horizontal,has a horizontal component of70 cos(20°) = 65.778 (rounded)
If the initial velocity is v, at an angle x to the horizontal, then the vertical component is v*sin(x) and the horizontal component is v*cos(x).

The vertical velocity component changes due to the effect of gravity, which causes acceleration in the downward direction. The horizontal velocity component remains constant because there are no horizontal forces acting on the projectile (assuming air resistance is negligible).
Yes, the horizontal component of a projectile's velocity is constant and independent of time as long as there is no external horizontal force acting on the object.
If air resistance is neglected, the motion of an object projected at an angle consists of a uniform downward acceleration due to gravity combined with constant horizontal motion at a constant velocity. The vertical component of the velocity changes uniformly due to gravity, while the horizontal component remains constant throughout the motion.
The vertical component of the acceleration vector is the acceleration due to gravity (9.81 m/s^2 downward). The horizontal component of the acceleration vector is zero since there is no acceleration acting in the horizontal direction (assuming no external forces).
The vertical component of velocity changes due to the influence of gravity, which accelerates the projectile downwards as it moves. The horizontal component of velocity remains constant because there is no horizontal force acting on the projectile, assuming air resistance is negligible.

In projectile motion, the only acceleration acting on the object is in the vertical direction due to gravity. This causes the vertical component of velocity to change over time while the horizontal component remains constant since there is no acceleration acting in the horizontal direction.
Divide the motion into a horizontal and a vertical component. The horizontal component won't be affected by gravity. The vertical component will get a downward acceleration of 9.8 meters per second per second.
A bullet shot horizontally will experience a vertical acceleration due to gravity of 9.8 m/s^2, which acts downward. However, since there is no vertical propulsion force acting on the bullet, the vertical motion is purely due to gravity.
In the usual simple treatment of projectile motion, the horizontal component of the projectile's velocity is assumed to be constant, and is equal to the magnitude of the initial (launch) velocity multiplied by the cosine of the elevation angle at the time of launch.
When a body is thrown horizontally with uniform speed, there is no change in the horizontal velocity, so the horizontal component of acceleration is zero. The only acceleration acting on the body is due to gravity in the vertical direction.
