B3-RT03: STACKED PACKAGES MOVING ON MOVING CONVEYOR BELTNET FORCE Various stacks of packages are traveling along a conveyer belt. At the instant shown below, all packages have the same velocity of 3 mv/s to the right. The packages do not slip on the belt. All masses are given in the diagram in terms of M, the mass of the smallest package. Rank the magnitude of the net force on each stack of packages. S 1T T 1 Je [ 0T 1] ol T T W B | Greatest .
