???????

(1 point) Consider the mass-spring system for mass \( 2.7 \mathrm{~kg} \), spring constant \( 4.4 \mathrm{~N} / \mathrm{m} \), and an oscillating force \( 2.3 \cos (\omega t) \) Newtons. That is, \[ 2.7 x^{\prime \prime}+4.4 x=2.3 \cos (\omega t) \] What positive angular frequency \( \omega \) leads to resonance? \( \omega=\quad \) help (numbers) What is the resonance part of the solution (without the complementary solution): \( y_{p}= \) help (formulas)
