In summary, the conversation discusses the need for more information about an elastic collision, with suggestions to look it up in physics books and apply relevant equations. The drawing is also mentioned, with a question about the tangent line and the direction of impulse in the absence of friction.

Then this is covered in every first year physics book and many other places. Look it up please. Elastic two-body collision. You can report your work and result if you desire

The drawing could use some commentary. There is a horizontal line drawn through the center. All of the angles are referenced to that line.
When the two objects touch, is this line supposed to be tangent to both of them?
In the absence of friction, what is the direction of the impulse of momentum that is transferred between the objects at the instant of the collision?

1. What is a rigid body?
A rigid body is an object that does not deform or change shape when subject to external forces. In the context of collisions, rigid bodies are typically considered to be solid objects that do not bend or break upon impact.
2. How is the angle of two rigid bodies determined after a collision?
The angle of two rigid bodies after a collision is determined by calculating the direction and magnitude of the forces acting on each body during the collision. This information can be obtained through measurements and calculations using principles of physics and mathematics.
3. Can the angle of two rigid bodies change during a collision?
Yes, the angle of two rigid bodies can change during a collision due to the transfer of energy and momentum between the bodies. The change in angle will depend on the specific properties and orientation of the bodies involved, as well as the forces acting on them.
4. How does the angle of two rigid bodies affect the outcome of a collision?
The angle of two rigid bodies can greatly impact the outcome of a collision. Different angles can result in different forces and trajectories for the bodies, which can influence the amount of energy and momentum transferred between them. This, in turn, can affect the final velocities and directions of the bodies after the collision.
5. Are there any factors that can affect the accuracy of determining the angle of two rigid bodies after a collision?
Yes, there are several factors that can affect the accuracy of determining the angle of two rigid bodies after a collision. These include measurement errors, assumptions made in the calculations, and external factors such as friction and air resistance. It is important to carefully consider and account for these factors in order to obtain the most accurate results.
