You can't determine the velocity of a softball without more information. Velocity is a measure of speed and direction, and a softball's velocity can vary greatly depending on:

* How it's thrown: A pitcher's fastball will have a much higher velocity than a casual toss.

* The speed of the batter: A hit ball will have a different velocity than a ball caught in the air.

* Air resistance: The velocity of the softball will change as it moves through the air.

To find the velocity of a softball, you would need to know:

* The speed: How fast the ball is moving.

* The direction: Which way the ball is traveling.

For example, you might say: "The velocity of the softball is 80 mph eastward."
