hmm, im not quite sure then but i as well thought it was 0.70 hz
what about this one?
A 1.0 kg weight suspended from a spring is pulled to 0.25 m below its equilibrium point.
If the spring has a spring constant (k) of 50.0 N/m , at what rate will the mass accelerate when it is released?
200 m/s2
12.5 m/s2
6.5 m/s2
2.7 m/s2
2.7 ?
