Two identical blocks fall a distance H. One falls directly down; the other slides down a frictionless incline. Which has the larger speed at the bottom?
 
  1.The one falling vertically
  2.The one sliding down the incline
  3.Both have the same speed
  4.Cannot be determined

Question 2

Two identical blocks are pulled as shown along rough horizontal surfaces with the same coefficient of friction. Both are pulled at constant speed v. 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 mass m
  7.Impossible to determine without knowing the speed v
  8.Impossible to determine without knowing the angle of T2
  9.Impossible to determine for 2 of the reasons above
  10.Impossible to determine for some other reason
