A 2.0kg mass attached to a spring makes 10 oscilations in 21.6s; its amplitude is .0320m
Find spring constant k. My question about this part is
frequency=(#of oscillations)/(#of seconds to complete) right?
So f=10/21.6s =2.16Hz?
So if k=m\omega^2
k=2(2\pi*2.16)^2
IT's the wording that gets me...
And to find speed at x=o I use conservation of mech energy
\frac{kx_m^2}{2}=\frac{mv^2}{2}+\frac{kx^2}{2}
and I can eliminate .5kx^2 since x=0...
