Muhammad does an experiment where he uses a string attached to a spring scale to pull horizontally on a wooden block of unknown mass. He uses a second spring scale to push down on the block, exerting a series of forces F1 on B on it. For each of these downward forces, he pulls horizontally on the spring scale attached to the string to determine the maximum force F2 on B he can exert on the block in the horizontal direction before it slides. He records all of his measurements in the table below. Determine (a) the mass of the block and (b) the coefficient of friction between the block and the table.
