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

Once thought to have neurofibromatosis, Joseph Merrick (also known as "the elephant man") is now, in retrospect, thought by clinical experts to have had Proteus syndrome. This endocrine disease causes continued and abnormal growth of the bones, muscles, skin, and so on and can become completely debilitating with severe deformities occurring anywhere on the body.
