• positive

• negative

• yes, because it's velocity is changing

• yes, because it's speed is changing

• no, because it's speed is not changing

This means that for every second the cheetah is running the velocity

• increases by 9.3m/s

• decreases by 9.3m/s

• increases by 9.3s

What is the change in velocity?

• -15.3m/s

• 15.3m/s

• 8s
