Homework Statement
Harmonically fluctuating object. It`s full energy (E) is 3*10-5 J. Maximum force (F) on object is 1.5 * 10-3N. Period is 2 seconds (T) and starting phase (ƒ) is 60°. Need to write equation for these fluctuations.
E = 3*10-5 J
F= 1.5 * 10-3N
T = 2 s
ƒ = 60°
Homework Equations
I know this formula X (fluctuation formula) = A*cos(ω*t + ƒ)
ω - fluctuation angular frequency
t - time
ƒ - starting phase
The Attempt at a Solution
I found this formula E/F = A/2. Looks like I can calculate A (max amplitude). So 3*10-2/1.5 * 10-3 = A/2 A = 0.04 m (I guess it is in meters?)
So, how can I calculate ω now? Edit: just found ω = 2Π/t, could this be right?
