Force and Translational Dynamics
Two objects, A and B, have masses of 2 kg and 3 kg, respectively. They are initially at rest. An external force of 10 N is applied to object A. Calculate the change in the center of mass velocity of the two-object system after 2 seconds, assuming no other external forces act on the system.
A person jumps off a boat. Identify all action-reaction pairs involved in this scenario.
A block rests on a table. Which of the following is the action-reaction pair described by Newton's Third Law?
