Problem
Block A (mass 1.0 kg) rests on top of block B (mass 3.0 kg), which sits on a horizontal table. A horizontal push is applied to block A, and static friction prevents slipping between the blocks; friction between block B and the table is negligible. Identify all distinct action–reaction force pairs that involve block B. For each pair, state both the force acting on block B and its partner force exerted by block B, specifying the other object in each case.
