sleeps help in muscle recovery, so when we do not sleep or lack of sleep it leads to inflammation in muscles, which causes pain in muscles.
Sleep and pain both have relation.
Poor sleep schedule causes this muscle pain intensity to increase
In addition to inflammation and pain, it also decreases the tolerance of pain.
As we know sleep heals the muscle and fasten any injury caused to muscle, lack of it causes the healing slow.
This inflammation in muscle causes poor performance in the body.

This is used by individuals in the real world in order to regulate crying in front of everyone for example. Calming ourselves down by breathing is another good example of regulating emotion which plays into emotional intelligence.
Hope this helps mate :D
Explanation:
Given that,
Initial speed of the billiard ball 1, u = 30i cm/s
Initial speed of another billiard ball 2, u' = 40j cm/s
After the collision,
Final speed of first ball, v = 50 cm/s
Final speed of second ball, v' = 0 (as it stops)
Let us consider that both balls have same mass i.e. m
Initial kinetic energy of the system is :

Final kinetic energy of the system is :

The change in kinetic energy of the system is equal to the difference of final and initial kinetic energy as :
So, the change in kinetic energy of the system as a result of the collision is equal to 0.
