The standard equation can be given as:
Transfer function = w^2/(s^2+2wys+w^2).
On equating given equation with standard equation we get this,
2wy = 2.
=>w = freq.
=>y = damping ratio.
From equation w^2 = 4.
=>w = 2.
Then 2*2*y = 2.
y = 2/4 = 0.5.
Transfer function = w^2/(s^2+2wys+w^2).

Please, someone, tell what is the difference between:
Damping ratio, Damping coefficient, Damping factor.
Damping ratio, Damping coefficient, Damping factor.

2s = 2s X Damping factor X 2.
So, DAMP FACT = 1/2 = 0.5.
So, DAMP FACT = 1/2 = 0.5.
