In an experiment on Atwood's machine, you collect data on the total mass of the system and the measured acceleration of the system. You plot the total mass versus the reciprocal of the experimental acceleration and obtain the graph shown below. What is the best estimate of the net force acting on the system? (Express your answer to three significant figures.)
