Homework Statement
A 1.86 g piston is attached to a rotating disc. The radius is 25.5 cm when the disc is stationary. A spring attached to the piston has a spring constant of 31.3 N/m. The piston is rotating at a frequency of 10 Hz. How har will the piston move outward
k = 31.3
r = 25.5 cm = 0.255 m
Frequency = 10 Hz
m = 1.86 g
Homework Equations
1/2kx^2 = Es
ac = v^2/r
W = change in Energy
The Attempt at a Solution
I really don't even know where to start. Please help. How am I supposed to relate frequency to speed?
