An object in simple hormonic motion starts at amplitude ao. due to dampening, after 30 sec, the object is now at 30% of its original amplitude. what is the dampening constant of this system? a. 11s b. 25s c. 33s d. 84s e. 55s

C ) 33 s.

Explanation:

In simple harmonic motion damping of amplitude  is logarithmic which is expressed as follows

A/A₀ = .3 (given ) , b is damping constant and t is time which is 30 s here.

ln .3 = -b / 30

1.2 = b / 30

b = 36 s 0r 33 s

im sorry i dont know

i already answered it by 34/s
