A baseball is traveling (+20 m/s) and is hit by a bat. It leaves the bat traveling (−30 m/s).
What is the change in the velocity?
Remember that direction is what makes velocity different than speed.

The change in velocity can be calculated by subtracting the initial velocity from the final velocity.
Final velocity - Initial velocity = Change in velocity
(-30 m/s) - (+20 m/s) = (-50 m/s)
Therefore, the change in velocity is 50 m/s.
