POF #1

Problem of the Fortnight #1

Elevated

You are in a stationary elevator having a glass ceiling.  You look up and are horrified to see that a brick has been dislodged from the top of the elevator shaft.  What should you do to minimize your chance of being injured:  send the elevator up, send it down, or do nothing?

Assume that the up and down speeds of the elevator are the same and that it attains these speeds very quickly after starting in motion.

 

Due:  Wednesday, November 20, at noon.
