Question
would the answer be C due to newtons law of two equal forces acting opposite to each other, or would the answer be E due to mass*a (a=1)?
Problem 6: Two boxes with different masses, M = 60 kg and m = 40 kg, are resting against each other on a flat horizontal icy (frictionless) surface. An external force, F = 1100 N, is applied to the larger mass as shown in the figure below: If block M pushes on block m with force F12, and block m pushes on block M with force F21, which of the following statements is true (neglecting friction)?
