physic question help for driving frequency?
A 1.350 kg mass is suspended from a spring, with a spring constant of 181.0 N/m. Find the driving frequency which would cause resonance. Hint: The frequency of resonance is simply the natural frequency of the system.
i have gotten 7.28Hz so far, but that is wrong and i am unsure as to what im doing wrong.
if you could help me id appreciate it very much!

Resonance means the natural frequency (wn) equals the driving frequency w
so w/wn = 1
natural frequency = sqrt(k/m) = sqrt (181 N/m / 1.350 kg)
N/m / kg = m/s^2 /m = 1/s^2
