i need help

Tuning forks are used in the diagnosis of nervous afflictions known as large-fiber polyneuropathies, which are often manifested in the form of reduced sensitivity to vibrations. Disorders that can result in this type of pathology include diabetes and nerve damage from exposure to heavy metals. The tuning fork in the figure below has a frequency of 142 Hz. The tips of the fork move with an amplitude of 1.23 mm. Find the maximum speed of the tips. m/s Find the maximum acceleration of the tips. (Give your answer as a multiple of g.) g

Explanation / Answer

a)w=2*pi*f=2*pi*142=892.212 rad/s maximum speed=A*w=1.23*10^-3*892.212=1.097 m/s b)maximum acceleration =a*w^2=1.097*892.212=99.89 g
