Center on mass trigonometric trick

In summary, the conversation is about center of mass problems involving collisions and the use of trigonometric tricks in finding solutions. The speaker is looking for advice or tips on approaching these types of problems, specifically in classical physics. They also mention a specific problem involving two balls colliding in the center of mass frame and the lab frame.

hey there I am doing a lot of center of mass problem most of them with collisions , and most of the solutions I see, have a big part of "trigonometric trciks", like the way u watch the vectors in cm frame and the way in the lab frame. does anyone met this kind of solutions and have some tricks or advices that wil be great.
btw I am in classical physics (course)
thx

well it pretty hard to explain but ill just say that the proble,m is of two balls striking each other and in the first graph is the cm graph the other one is the lab frame.
I hope it will help/ and there are a lot of problems like that

What is the "center on mass trigonometric trick"?

The "center on mass trigonometric trick" is a mathematical technique used to calculate the center of mass of a system with multiple objects or particles. It involves using trigonometric functions to determine the coordinates of the center of mass.

How is the "center on mass trigonometric trick" used in science?

This technique is commonly used in physics, engineering, and astronomy to determine the center of mass of bodies such as planets, stars, and spacecraft. It is also used in mechanics to analyze the motion of objects.

What are the benefits of using the "center on mass trigonometric trick"?

The "center on mass trigonometric trick" allows for a more accurate and efficient calculation of the center of mass compared to other methods. It also takes into account the distribution of mass within a system, making it useful for complex systems with irregular shapes.

Are there any limitations to the "center on mass trigonometric trick"?

While this technique is useful in many cases, it may not be applicable to systems with continuously changing mass or those with infinite dimensions. It also assumes a homogeneous distribution of mass within the system.

Can the "center on mass trigonometric trick" be used for 2D and 3D systems?

Yes, the "center on mass trigonometric trick" can be used for both 2D and 3D systems. In 2D, it involves the use of sine and cosine functions, while in 3D, it also involves the use of the tangent function. The same principles apply in both cases, but the calculations may be more complex in 3D systems.
