Here are the formulas that describe projectile motion:

Once the object leaves the table, it experiences a downward acceleration equal to gravity. Thus the vertical velocity(Vy) is continually increasing. The horizontal velocity(Vx) remains constant and is equal to Vxo.The two vectors Vx and Vy are added together to get the velocity at each point on the path.	If an object is pointed at an angle, the motion is essentially the same except that there is now an initial vertical velocity(Vyo). Because of the downward acceleration of gravity, Vy continually decreases until it reaches its highest point, at which it begins to fall downward.
