The figure shows two blocks, released from rest, connected by a light string passing without slipping over a pulley with moment of inertia 0.032 kg-m² and radius 0.1 m. The coefficient of kinetic friction between the block and the table is 0.38. Using energy methods, find the blocks' speed after they have moved 0.22 m if M = 5.2 kg and m = 7.3 kg. M V= A m/s m Record your numerical answer below, assuming three significant figures. Remember to include a "-" as necessary.
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).
