  The gravitational potential energy of the system is greatest at A.
   
  b.
  The elastic potential energy of the system is greatest at O.
   
  c.
  The rate of change of momentum has its greatest magnitude at A and B.
   
  d.
  The rate of change of gravitational potential energy is smallest at O.
   
  e.
  The rate of change of gravitational potential energy has its greatest magnitude at A and B.

Question 2

Which is the correct ranking in order of increasing angular frequency ?
 
 
 
   
  a.
  hoop, cylinder, sphere
   
  b.
  cylinder, sphere, hoop
   
  c.
  sphere, cylinder, hoop

Drug abusers experience the following scenario: The pleasure given by their drug (or drugs) of choice is so strong that it is difficult to eradicate even after years of staying away from the substances involved. Certain triggers may cause a drug abuser to relapse. Research shows that long-term drug abuse results in significant changes in brain function that persist long after an individual stops using drugs. It is most important to realize that the same is true of not just illegal substances but alcohol and tobacco as well.
