Walk the Planck
Walk the Planck
You have been captured by a band of Pirates who are going to make you walk the plank. However, these Pirates are from Seton Hall in New Jersey, so they are both intelligent and compassionate. They will grant you your freedom if you can solve this physics problem. They will give you a board with a certain length and mass. A large portion of the board will protrude over the water, but a small part of it will be resting on the deck of the ship. You must figure out the exact amount of mass you need to put on the ship end of the board so that you can walk all the way to the other end and walk back. If you try to use too much mass you will be sent to the brig and if you don't use enough mass, you will cause the board to rotate off the ship when you get too far out.
