The maximum velocity is A*w and the maximum acceleration is A*w^2.
A is the amplitude (1.5*10^-8 cm) and w s the angular frequency, 2*pi*f
The same formulas apply to both of your questions.
The air pressure variations in a sound wave cause the eardrum to vibrate. Find the maximum velocity and acceleration of the eardrum for vibrations of amplitude 1.5 10-8 m at a frequency of 19.0 Hz.Repeat (b) for the same amplitude but a frequency of 19.0 kHz.
