How to deform/flex straight part to become curved?

Hi everyone, I was wondering if someone can kindly help me with this.

I would like to uniformly flex the straight part to match the inner radius of the curved part. I've drawn the curved part for reference only. I'm only looking to have the straight part end up with the same radius as the inside of the curved piece.

Please see image below - I've also attached the solidworks file.

If someone can please help answer this question with the steps that would be much appreciated. Thanks everyone in advance.
