Answer:
One mass's kinetic energy is 4 times the other.
Step-by-step explanation:
The formula for kinetic energy is 
Where
KE is the kinetic energy
m is the mass
v is the velocity
- Now, let mass of the first be m (second is identical so mass of 2nd is m as well)
- Let velocity of the first one be v. Since 2nd one is travelling twice as fast, its velocity will be 2v
<u>KE of 1st mass is:</u>

<u />
<u>KE of 2nd mass is:</u>

Hence, the kinetic energy of the 2nd mass is 4 times the first.

Answer:
I think
"Quadriplegia" would go with a "spinal cord injury".
Quadriplegia is a spinal cord injury that causes you to lose feelings in all four limbs.
A "knee injury" would go with "Limited ability to walk and run."
"Headaches" with "traumatic brain injury."
