2-D Dynamics Homework || Problem 3: Block At Rest With Spinning Block

Not being able to do a physics homework problem is one of the worst things ever. Especially since a lot of your time can be wasted. Sometimes you just want to find a reference to your problem to see what you are doing wrong. The worst thing is that these are often behind paywalls and often times not even helpful. Students shouldn't have to pay in order to see references on how to solve problems so I am recording myself doing my problems in hopes it helps other people who are stuck on similar problems. I apologize in advance for the super low quality (I cannot spend that much time editing these) but I hope they are helpful.

Mass m1 on the frictionless table of the figure is connected by a string through a hole in the table to a hanging mass m2. With what speed must m1 rotate in a circle of radius r if m2 is to remain hanging at rest?
