a = v^2/r
v T = 2 pi r
so
v = 2 pi r/T
v^2 = (2 pi)^2 r^2/T^2
a = v^2/r = (2 pi)^2 r /T^2
divide T by sqrt 3
a' = (2 pi)^2 r / (T^2/3)
On your first day at work for an appliance manufacturer, you are told to figure out what to do to the period of rotation during a washer spin cycle to triple the centripetal acceleration. You impress your boss by answering immediately.
Express in terms of T.
Equation I believe that needs to be used is a = 4π²r/T²?
