There are two masses hanging down off the sides of a table connected with a spring between them. Describe what will happen and what value the spring scale S will read (a spring scale will read the tension in the wire.) in fig.1 below if m 1 = m 2 = 1 kg and if m 1 = 1.2 kg, m 2 = 1 kg. For the second case show your work and obtain an acceleration numerically, if you think there will be one, along with the spring scale reading. (Ignore the mass of the scale, the pulleys, and the string.)
