## Homework Statement

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.

## Homework Equations

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.
