A pulley has a negligible mass (that means, the radius is not relevant). It is supported with a pin at the center (and is free to rotate). A rope goes over the pulley. Block A, which has a mass of 5.723 kg is connected to one side of the rope. On the other side, Block B, with a mass of 12.602 kg is connected. The system is released from rest. What is the speed of block B, after B has traveled 0.716 m? Please enter a positive value in m/s (but without units) regardless of the direction of the motion of B
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).
