When responding to sound, the human eardrum vibrates about its equilibrium position. Assume an eardrum is vibrating with amplitude of 6.70 x 10-7 meter and a maximum speed of 2.83 x 10-3 m/s.
(a) Find the frequency of the eardrum vibration? (in Hz)
Hz
(b) Find the maximum acceleration of the eardrum?
