1. A 50,000-kg train car moving at 2 m/s collides and connects to another identical car initially at rest.
-What is the momentum of the first train car before the collision?
-What is the final velocity of the two connected train cars?
- Is the momentum being conserved through out the collision? Explain why.
-Is the kinetic energy being conserved through out the collision? Explain
why.
-Is this collision an elastic or inelastic collision? Explain why.

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation

a. spokes of a wheel.

as indicated in the question radial contains rad, also found in radius, so the fracture's would span the radius.
