\begin{aligned} & \implies 2mgy + (I+mx^2)\omega_x^2 \leq (I+ml^2)\omega_0^2 \\ & \implies 2mgy + (I+mx^2)\left( \dfrac{I+ml^2}{I+mx^2}\omega_0 \right)^2 \leq (I+ml^2)\omega_0^2 \\ & \implies 2mgy \leq (I+ml^2)\omega_0^2 - \frac{(I+ml^2)^2}{I+mx^2}\omega_0^2 \\ & \implies 2mgy \leq \underbrace{(I+ml^2)\omega_0^2}_{\geq 0} \underbrace{\left[ 1-\dfrac{I+ml^2}{I+mx^2} \right]}_{<0} \leq 0 \\ & \implies y \leq 0
