B. Teens are still growing and require more energy for building bones and muscle.
Answer:
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
So the problem ask to calculate the magnitude of the average force applied to the ball if its mass is 0.2kg changes its velocity from 20m/s to 12m/s and the time contact with the ball with the wall is 60 ms. In my calculation the best answer would be 107N.
