When you pull an object, such as a table, across the floor, the forward force by you on the table is equal but opposite to the backward force by the table on you.
 
  It seems as though these two forces should balance out, so that the table can't be moved. But the table does move, because
  A) the force by you on the table is larger than the force of the table on you.
  B) the floor pushes forward on the table.
  C) the momentum always acts in a forward direction.
  D) only one of these two forces actually acts on the table.
  E) Newton's laws do not apply to the table considered as a separate object.

  A) 8 J.
