HELP PLEASE! describe what would happen if while wearing roller skates you pushed as hard as you could against a wall why does this happen​

You'd get a concussion.

Explanation:

the impact from you hitting the wall at such a velocity while wearing roller skates would cause a concussion due to TBI or traumatic brain injury. See a simple bump, blow, or jolt to the head can cause a concussion A concussion can also occur from a fall or a blow to the body that causes the head to move back and forth rapidly.

if your pushing away from a wall, you would move at a rapid-ish speed. if you were to hit a wall you'd end up with a concussion.

Explanation:

velocity helps with the first one and concussions are caused when your head is forced to move at a rapid rate back and forth
