In a projectile motion situation where an object is launched at a 45潞 angle, if x is the horizontal direct?

In a projectile motion situation where an object is launched at a 45潞 angle, if x is the horizontal direction and drag is neglected, what is the acceleration of the object in the x direction a few seconds after being launched?In a projectile motion situation where an object is launched at a 45潞 angle, if x is the horizontal direct?The HORIZONTAL component of the velocity will remain constant throughout the flight. And since the velocity is constant, then its acceleration is zero.



Hope this helps.In a projectile motion situation where an object is launched at a 45潞 angle, if x is the horizontal direct?Zero, gravity works vertically (and down), that is in the negative y direction. Gravity does not act horizontally, or in x.
