Damping is negligible for a 0.164 kg mass hanging from a light 6.70 N/m spring. The system is driven by a force oscillating with an amplitude of 1.77 N. At what frequency will the force make the mass vibrate with an amplitude of 0.500 m? There are two possible solutions, enter one of them.
I think I have too use A=(F/m)/((w^2-w0^2)^2+(bw/m)^2)^1/2 where w is omega.
The Attempt at a Solution
The problem I am having is understanding this equation because b is not given and I do not know what that different angular frequencies stand for or if I can use w=(k/m)^1/2. Solving it isn't a problem I just can't understand the equation, my prof did a terrible time explaining it and my text isn't making sense too me. Thank you too whomever in advance.
