When a person is involved in a car accident, why is the likelihood of injury greater in a head-on collision as opposed to being hit from behind? Answer using the concepts of relative velocity, momentum, and average force. (Select all that apply.)

1. The change in momentum is greater in the head-on collision.

2. The momentum of the driver relative to the ground is greater in a head-on collision.

3. The velocity of the driver relative to the ground is greater in a head-on collision. 4. The average force on the driver is greater in the head-on collision.

5. The collapse of the crumple zone in the front of the car occurs only in the head-on collision.

well I know from when crashes happen the head is most injured and if it ask why the front and not from behind I would say bc when u crash u go forward which u can get whiplash, hit you head etc so whichever one explains that XD
