Two blocks with mass m2 > m1 are pulled as shown along rough horizontal surfaces with the same coefficient of friction. Both are pulled at constant speed, but v2 < v1. Which tension force does more work moving the block a distance D along the surface?
 
  1.T1
  2.T2
  3.Neither; both do zero work
  4.Neither; both do the same amount of negative work
  5.Neither; both do the same amount of positive work
  6.Impossible to determine without knowing the masses
  7.Impossible to determine without knowing the speeds
  8.Impossible to determine for some other reason

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
