When responding to sound, the human eardrum vibrates about itsequilibrium position. Suppose an eardrum is vibrating with anamplitude of 6.70 10-7 m and a maximumspeed of 2.70 x 10-3 m/s.
(a) What is the frequency (in Hz) of the eardrum's vibration?
(b) What is the maximum acceleration of the eardrum?
