Consider a resonator with ω0 = 100 rad/sec and a Q factor of 100. Calculate the time takes it to settle within 2% of the final value when excited with a unit force.

8 s

Explanation:

Damping factor, F is given by

where Q is quality factor

Also, we know that the settling time, T is given by

where W is the resonant frequency.and substituting the first equation here we get

Since it takes 2% of final value to settle and considering 100 rad/s for resonant frequency and taking quality factor of 100 then  

answer: i don't know the answer good luck

explanation:

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
