When responding to sound, the human eardrum vibrates about its equilibrium position. Suppose an eardrum is vibrating with an amplitude of 6.75 10-7 m and a maximum speed of 2.98 10-3 m/s.
(a) What is the frequency (in Hz) of the eardrum's vibration?
Hz
(b) What is the maximum acceleration of the eardrum?
m/s2
