Physics: Newton Law of Motion Question? I am a bit confused about this elementary question. If anyone can guide me in the right direction, I would appreciate it. Picture: http://tinypic.com/r/14w84g1/7" 2 boxes are placed next to 1 another on a horizontal surface. The box on the left has a mass of 5 kg while the box on the right has a mass of 2 kg. Assume that there is no friction is negligible. By pulling on a horizontal string attached to the 2 kg box, Stephane is exerting a force T to the right, while you are exerting a force F to the right by pushing on the 5 kg box. Using F = 12 N and T = 2.0 N, (a) Determine the acceleration of the 2 kg box. [ There is an acceleration exerted on the 2 kg box by the 5 kg. Is this 12N/ 5 kg or 2.4 m/s^2. The tension applies solely to the 2kg box and is 2 N/2 kg or 1 m/s^2. The net acceleration should be 3.4 m/s^2. If that is the case, then the 2 kg box would be pulled by itself. Thus is the total net acceleration 2.4 m/s^2 because that acceleration outweighs the tension on the 2 kg box?] (b) Which box experiences the largest net force in this situation? [Should be the same based on part a?] (c) Determine the magnitude of the force exerted by the 2 kg box on the 5 kg box in this situation. If F = 10.0 N and T = 10.0 N, (d) Determine the acceleration of each of the boxes now. Thank you in advance.
