Trace the complete execution of the merge sort algorithm when called on the array below. Show the sub-arrays that are created by the algorithm and show the merging of sub-arrays into larger sorted arrays.

only #2 represents an object at rest on a table.

in #1, there is no normal force due to the table; the object is accelerating downward.

in #3, the vertical forces are not balanced; the object is accelerating downward.

in #4, neither the vertical nor the horizontal forces are balanced. the object is accelerating upwards and to the right.
