Two teams of four members each engage in a tug of war. Each of the first team’s members has an average mass of 62.0 kg and exerts an average force of 1317 N horizontally. Each of the second team’s members has an average mass of 68.0 kg. The second term pulls with a larger force so that the acceleration of the two terms is 0.169 m/s2. What is the average force exerted in the horizontal direction by each member of the second term? Whoever is answering this I truly appreciate you <3

Does changing the mass of the object affect the acceleration? I was to conduct an experiment where the motion of an object sliding on an inclined air track under the influence of gravity is observed. In order to demonstrate the effects of force while minimizing friction, the air track has lines of holes drilled along the top faces. My thought process: because f=ma I thought yes, but I have also gathered data that shows me that increasing mass does not necessarily mean increasing/decreasing a.
