7. Pages 62-63. Problem 3.8 The fall of a coffee filter. Parts of this problem could be more clearly stated. Part of the difficulty is that the timer didn't start exactly when the filter was dropped. So we don't know when t = 0. The easiest way to analyze the fall of the coffee filter is to determine the velocity v from part (a) and take it to be the initial velocity at t = 0.2302 with height y = 0.4164. Take the time difference between the different measurements to be 0.0247 or 0.0248; the difference is not significant.

22. Page 289. In the listing for pressure(), the denominator should not include the area factor. Thus, this line should be
return 1 + virialSum/(2*t*N*temperature);
We thank Amy Bug for pointing out this error.
