Answer:

try this answer 20 x 0.4=8

Answer:

Explanation:

The soccer ball that was kicked will have momentum 0.4(20) = 8 kg•m/s before the collision and 0 kg•m/s after the collision.

The second soccer ball will have momentum 0 kg•m/s before the collision and 8 kg•m/s after the collision.

If the collision is head on (not a glancing blow) and masses are identical, the two balls will exchange momentums.
