A cylindrical room is rotating fast enough that two small blocks stacked against the wall do not drop. The mass of block A is 4 kg and that of block B is 3 kg. a) Draw a diagram of the wall and of blocks A and B. Indicate the direction of the acceleration of block B at the instant shown in the figure. If it is zero, state that explicitly. b) Draw separate free-body diagrams for blocks A and B and label the forces as described on page 85. c) Identify any third-law companion forces on your diagrams d) Rank the magnitudes of all the horizontal forces that The cylinder is rotating about this axis A B mA = 4 kg mB = 3 kg you identified above in order from largest to smallest. Explain your reasoning. e) Determine the magnitude of each of the vertical forces on block A. If it is not possible 983 39/1980
