In the figures below, identical boxes of mass 10kg are moving to the right on a flat surface. The same magnitude (amount) of force, F, is applied to each box for the distance, d, indicated in the figures. Rank
these situations in order of the work done on the box by F while the box
is moving the indicated distance to the right. In this case, direction is
important. Explain your reasoning. *
*

A. A=B > C > D=F > E
B. B=D > A=C=E=F
C. B > A=E > C > D=F
D. All the same
E. All zero
F. Cannot determine
