6. There are three types of collisions that tend to happen frequently in soccer:
A) Headers (when a ball makes contact with a head)
B) Collisions between players' heads
C) when players hit the ground.
How would the amount of force on the head compare to the amount of force on the object it collides with, in each system A, B, and C?
