If there are 3 blocks weighing 20 kgs each and placed next to each other on a frictionless floor, and I exert 10 N, all 3 blocks will still move right? Do all the boxes recieve a 10N push since there is no friction to reduce the force as it transfers? But do I only get pushed back 10N due to reaction force? Finally do the same concepts apply if the masses are 1million kgs? Thanks!
