Objects A and B, of mass M and 2M respectively, are each pushed a distance d straight up an inclined plane by a force F parallel to the plane. The coefficient of kinetic friction between each mass and the plane has the same value mk. At the highest point,
 a. KA > KB.
  b. KA = KB.
  c. KA < KB.
  d. The work done by F on A is greater than the work done by F on B.
  e. The work done by F on A is less than the work done by F on B.
