(Figure 1) shows an Atwood machine that consists of two blocks (of masses m and my) tied together with a massless rope that passes over a fixed, perfect (massless and frictionless) pulley. In this problem you'll investigate some special cases where physical variables describing the Atwood machine take on limiting values. Often, examining special cases will simplify a problem, so that the solution may be found from inspection or from the results of a problem you've already seen. For all parts of this problem, take upward to be the positive direction and take the gravitational constant, g, to be positive. Figure 71. Let's be the magnitude of the tension in the rope connected to the block of mass my. and let 12 be the magnitude of the tension in the rope connected to the block of mass my Which of the following statements is true? O Th is always equal to T2- 72 is greater than Ij by an amount independent of velocity. O T2 is greater than 7, but the difference decreases as the blocks increase in velocity. O There is not enough information to determine the relationship between 7) and T2. Submit Request Answer Part B Now, consider the special case where the block of mass mij is not present. Find the magnitude, ?", of the tension in the rope. Try to do this without equations; instead, think about the physical consequences. View Available Hint(s) IVO ? T = Submit
