Ijust want to make sure: 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.

is it:

50 m/s 30 m/s 20 m/s or 10 m/s

50m/s

Step-by-step explanation:

We assum the direction the baseball is travelling to the bat is the positive direction at 20 m/s and is hit in the opposite at a faster speed. The change in velocity is the final velocity minus the initial velocity:

The change in velocity is 50m/s

the answer is a
