A baseball is traveling with a velocity of 40 m/s. If the acceleration is -2.0 m/s/s, what does this tell us about the baseball's velocity?

• it is slowing down

• it is maintaining velocity

• it is speeding up

• I don't know

You are skydiving with a velocity of -15 m/s. If acceleration due to gravity is -9.8 m/s/s, what does this tell us about your velocity?

• you are slowing down

• you are maintaining velocity
