Today, we'll perform a lab which will demonstrate the conservation of momentum in an explosion.  The lab has two parts:
  • In the first set-up, two carts of different known masses are placed touching each other on a track.  When you push a button on one of the carts, they will explode apart from each other.  You must figure out where on the track to place the carts so that they reach opposite ends of the track at the exact same time.  After doing the calculation, you'll perform the experiment to verify your results.  
  • In the second set-up, you'll use a similar set-up to determine the unknown mass of a bag of sand.  
Homework:  Study for Unit Test on Momentum - Monday, March 9th.  Make sure you've completed all of the assigned problems.  If you have any questions about this material, you must ask before the weekend.
