rsaad said:CM= (R1m1+R2M2)/M1+M2
because CM=0, I get M1 R1 = -R2 M2
which further gives me
R1= RM2 / (M2-M1)

Classical mechanics is the branch of physics that deals with the motion of macroscopic objects, such as everyday objects like cars and baseballs. It is based on Newton's laws of motion and can be used to predict the behavior of objects in a wide range of situations.
Coordinates in classical mechanics refer to the variables used to describe the position, velocity, and acceleration of an object. These can include position coordinates (such as x, y, z), velocity coordinates (such as vx, vy, vz), and acceleration coordinates (such as ax, ay, az).
Coordinates are used in classical mechanics to mathematically describe the position, velocity, and acceleration of an object in a given system. By measuring the values of these coordinates, we can make predictions about the behavior of the object and understand how it will move over time.
The most commonly used coordinate systems in classical mechanics are Cartesian coordinates (x, y, z), cylindrical coordinates (r, θ, z), and spherical coordinates (r, θ, φ). These systems allow us to describe the position and motion of an object in three-dimensional space.
Classical mechanics is the foundation of many other branches of physics, such as thermodynamics, electromagnetism, and quantum mechanics. It provides the fundamental principles and equations that govern the behavior of macroscopic objects and forms the basis for understanding more complex systems in other areas of physics.
