Question
can anyone confirm whether I am correct on these? just wanting to make sure they are correct.
For the first two is that you want the oscillation to dampen for the car and amplify for the piano. So I'm assuming I choose them right?
On the second I know kinetic energy is at a Max at O and therefore p=mv makes the magnitude of the momentum highest as well.
Which of the following response curves would you want for the springs of your car? Damped Oscillations Driven Oscillations Amplitude B C Frequency r (s) How 3 different oscillstors with ,-2 Hz behaves if left to oscillate on their own 2. B 3C 4. None of the above How the 3 driving tors repond te Which of the response curves would you want for the sound-board on a piano? Amplitude B C Frequency 2. B 3. C . None of the aboveExplanation / Answer
Yes you are right in all three question
1. In piano maxm amplificattion will occur at resonance hence option 1 is correct
2.In order to avoid maximum amplitude in car its responce curve should be like C
3.Since v is maximum at O hence KE and Momentum will be maximum here.
