A massless sping of spring constant k=74 N/m is hanging from the ceiling. A 490g mass is hooked onto the unstretched spring and allowed to drop. Find the amplitude and the period of the resulting motion.
Attempt:
F= -kx
x= A cos (wt)
w = sqrt(k/m) t
I'm trying to solve for A, but...
^^
thanks for the alternative method.
i had tried using the relevant equation, but i must have been tired or something, because i kept on getting the wrong answer.
i got it now though. thanks.
