Suppose a student carrying a flu virus returns to an isolated
college campus of 600 students. If it is assumed that the rate at
which the virus spreads is jointly proportional to number of

differential equation (don't solve) to determine the number of
students after t days if it...

No violation of the law of the conservation of momentum for an isolated system has ever been found. A consequence of the conservation of momentum is that the center of mass of an isolated system does not change. Einstein pointed out an apparent violation of the rule that the center of mass does not change for an isolated system. He...
