For simple harmonic motion
,
,
From the acceleration equation if you are given that then .
If at x = 2m, then from the velocity equation:
How can I solve for Amplitude and Period if I have the following data?
a=-4^2.x (ie. SHM)
x = 2m, speed = sqrt(10 )m/s
given I cannot use k=4 from a=-4^2.x
I was thinking to use v^2=k^2(A^2-x^2)
so 10=k^2(A^2-4) but then I have 2 unknowns?
