Exploration 6.2: The Two-Block Push

Please wait for the animation to completely load.

Two blocks are pushed by identical forces (position is given in meters and time is given in seconds), each block starting at rest at the first vertical rectangle (start).  The top block is twice the mass of the bottom block, m1 = 2m2 Restart.  The graphs and tables are initially blank.  Animation without Graphs and Tables.

  1. Which object has the greater kinetic energy when it reaches the second vertical rectangle (finish)? Why?
  2. Once you have answered the above question, click  Animation with Graphs and Tables to see if you were correct.  Consider both the graphs and the tables.
  3. If you were incorrect in your answer, can you figure out why you answered incorrectly?  What is the correct rationale you should have used to answer this question?  Use the graphs and tables where appropriate.
