two identical carts (750 g each) move along a frictionless track. One moves to the right at 1.2 m/s, the other to the left at 0.9 m/s. What is the momentum (in kg m/s) of the first cart (moving to the right)? (Assume right is the positive direction). B. What is the total momentum (in kg m/s) of the two cart system in the previous problem? (Right is positive)? C. If the carts collide and stick together, what is their final speed (in m/s)? (Remember: right is positive for this problem)
Rigid Body
A rigid body is an object which does not change its shape or undergo any significant deformation due to an external force or movement. Mathematically speaking, the distance between any two points inside the body doesn't change in any situation.
Rigid Body Dynamics
Rigid bodies are defined as inelastic shapes with negligible deformation, giving them an unchanging center of mass. It is also generally assumed that the mass of a rigid body is uniformly distributed. This property of rigid bodies comes in handy when we deal with concepts like momentum, angular momentum, force and torque. The study of these properties – viz., force, torque, momentum, and angular momentum – of a rigid body, is collectively known as rigid body dynamics (RBD).
