Molly's Meningitis Three-year-old Molly was brought to the emergency department crying. She had a stiff neck and high fever (40°C, or 104°F). Gram stain of her cerebrospinal fluid revealed Gram-positive cocci, generally in pairs. The attending physician diagnosed Molly with meningitis and immediately prescribed intravenous ampicillin. Unfortunately, the child's condition worsened, so antibiotic treatment was changed to a third-generation cephalosporin (ceftriaxone). Molly began to improve within hours and was released after 2 days. A report from the clinical microbiology laboratory 2 days later identified the organism as Streptococcus pneumoniae. The report also included antibiotic susceptibility results, which revealed that this strain of S. pneumoniae was resistant to ampicillin but remained susceptible to cephalosporin.

1) Make example plots of the kinetic and potential energies vs. sphere-magnet separation for the incoming ball. Fit the potential energy plot with an appropriate mathematical function. 2) Make example plot of the kinetic energy vs. the starting sphere-magnet separation for outgoing balls. 3) Using the last point on your potential energy plot of the incoming ball, calculate the initial potential energy of the outgoing ball at each starting position. 4) Why are the final kinetic energies of the outgoing balls greater than the initial kinetic energy of the incoming ball? 5) Where might energy be lost before, during, and after the collision? 6) For a given sphere arrangement (i.e., a fixed number of balls after the magnet), make five repetitions of your collision measurement and calculate the KE of the outgoing ball for each. Compute the mean and standard deviation of these KE and comment on likely reasons your measurements aren't all the same. Is this 'error' statistical or systematic? 7) Does the magnet-sphere potential have something about it that is analogous to the part of the Lennard-Jones potential that is repulsive? Can the distance between the sphere center and the magnet go to zero? 8) How does a Gauss gun compare to a chemical reaction?
