• A) 20 kg·m/sec

• B) -20 kg·m/sec

• C) 10 kg·m/sec

• D) -10 kg·m/sec

Multiple Choice

If a ball is thrown at -20 m/sec, what does the negative sign indicate?

• The ball is moving forward

• The ball is moving backward

• The ball is stationary

• The ball is accelerating.

Multiple Choice

Fill in the blank: The momentum of the BALL is equal to the momentum of the ________________.

• skateboarder

• ball

• car

• bicycle

Multiple Choice

If the momentum of the ball is 20 kgm/s and the skateboarder is 20 kgm/s, what can be concluded?

• A) They have different momentum.

• B) They have the same momentum.

• C) The ball has more momentum.

• 20 kgm/s

• -20 kgm/s

• 40 kgm/s

Multiple Choice

If momentum before equals momentum after, what is the total combined momentum of the ball and skateboarder after the ball was thrown? (20kgm/s + -20kgm/s = ?)

• 0 kgm/s

• 20 kgm/s

• -20 kgm/s

• 40 kgm/s
