Explanation:

Step1: Analyze the first blank

The system here consists of the medicine ball and the clown. To find the total momentum of the system before collision, we sum the momenta of the components. The momentum of the ball is 80 kg·m/s and the clown is 0, so it's the "total" momentum of the system.

Step2: Analyze the second blank

By the law of conservation of momentum, the total momentum before collision equals the total momentum after collision. So it should be 80 kg·m/s.

Step3: Analyze the third blank

After collision, the clown and ball move as a single unit, so their combined quantity is momentum (since we're talking about the 80 kg·m/s value).

Step4: Analyze the fourth blank

Before collision, the clown's momentum is 0 and the ball's is 80, so the ball has "more" momentum.

Step5: Analyze the fifth blank

The direction they move is the direction the medicine "ball" was moving (since the ball had momentum and the clown had none, the combined motion follows the ball's direction).

Answer:

1. total
2. 80
3. momentum
4. more
5. ball
