In general, for objects falling near the surface of the earth, the acceleration is -g = -9.8 m/s^2, no matter how long it takes to come down. The minus sign indicates downward acceleration

If you did not know the value of g (for example, if you were on an unknown planet), you could determine the acceleration (a) if you knew the launch velocity of the ball (V). The time it takes to come down (T) is given by

a T/2 = V
