d=1.15sin(wt) where w=2PI*135
v=d/dt displacement=1.15w cos wt
max speed 1.15mm*w
acceleration
a=d/dt v= 1.15 w^2 change the 1.15 to m, then divide by g.
Need help ASAP for this one, really hard.

Tuning Forks in Neurology 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 has a frequency of 135hz .
A) If the tips of the fork move with an amplitude of 1.15mm , find their maximum speed.
B)Find their maximum acceleration. Give your answer as a multiple of g.
Please any help would be appreciated!
