2. Relevant equations

Energy Equation

3. The attempt at a solution

As shown in the scan.

Is this the correct approach? I have a feeling that the velocity, v, needs to be used. I used the Energy Equation for this problem but wasn't sure if it was the right equation to address kinetic energy, potential energy, and rotational motion.

Please lead me to the right direction if I'm incorrect.

Thanks
