Man, boat, brick

December 17th, 2009

I set a little Fermi Problem for students yesterday – with the promise of a prize for the best written argument which answers these questions.

Man, boat, brick.

I’ll be judging the entries tonight and deciding on prizes in time for the last day of term. I might even publish the best entries here, but meanwhile, you can read an earlier version of this exercise (which was a slightly different problem) here and my solution to it is here (click to see it full size):

    you didn’t take any account of the drag of the water on the boat, but i am very impressed. the speed makes a lot more sense than mine did.
    this is fun, got any more!

    missed decimal place in brick vs my weight. speed should be 0.2 mph. all the best ian
