A 7kg plate with a radius of 1.4m is rotating at 63 rad/s around an axis perpendicular to its center. Another plate that is not rotating is dropped onto the first plate and their centers align. The second plate is 5kg, with a radius of .8m. What is the angular velocity of the two disks combined?

I am really confused with this problem.
What is my first step?
Thanks
Angular velocity refers to the rate at which an object rotates or revolves around a fixed point. It is typically measured in radians per second.
Angular velocity is a measure of rotational motion, whereas linear velocity is a measure of straight-line motion. Angular velocity takes into account the distance of the object from the axis of rotation, while linear velocity does not.
The angular velocity of weighted plates is affected by the mass of the plates, the distance from the axis of rotation, and the force applied to the plates. The shape and size of the plates may also have an effect.
Angular velocity is calculated by dividing the angular displacement of the object by the time it takes to complete that displacement. It can also be calculated by multiplying the angular frequency (in radians per second) by the radius of the rotation.
Angular velocity is used in various fields such as physics, engineering, and sports. In physics, it is important for understanding rotational motion and calculating the torque and angular momentum of objects. In engineering, it is used in designing and analyzing rotating machinery. In sports, it is used to measure the speed at which objects are thrown or hit, such as in baseball or golf.
