Two persons A and B who are at rest on an ice skating rink, push each other so that A acquires a velocity of 11.5 m/s towards North. If the mass of person A is 55 kg and that of B is 43 kg. What is the velocity acquired by B and in which direction? Your answer must be in the order Velocity / Direction.
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).
