Nanotechnology class, quantum review problem.

  1. Sep 7, 2012 #1
    1. The problem statement, all variables and given/known data

    Consider a football field. Standing along the sideline are 100 people, on person at each 1-yard hash mark. The first person weighs 30kg, the next 3kg, and so on up to 130kg. The people can only move in straight lines toward the opposite sideline. At a particular moment we are able to determine the distance of each of these people from the sideline to within 0.5 yards. Create a plot that shows the minimum uncertainty of the people's speed (m/s) at this moment vs. their mass (kg).

    2. Relevant equations

    This is in the review quantum chapter at the beginning of the book. There isn't much depth to it, Schrodinger's equation isn't even mentioned.

    3. The attempt at a solution

    I am actually not entirely certain what is going on to even set it up. I can't get a good mental picture in my mind of the situation. This indicates there is a relationship between velocity and mass, but I fail to see one. I would be very grateful to anyone who could help me see what this is more clearly.
