Block A (1 kg) sits on block B (2 kg), which rests on a table. The coefficients of friction between the two blocks are μs=0.5 and μk=0.1. The coefficients of friction between block B and the table are μs=0.7 and μk=0.3. a. If I push horizontally on block B, how hard do I need to push to get it to move? b. If I continue to push with that force on block B after it has begun moving, will block A move with the same acceleration? c. How hard must I push on block B (horizontally) to make block A slip?!
