Bouyancy and Locks
A cargo ship resting in a lock loses several containers
overboard which sink to the bottom of the lock. Will the water level in
the lock increase, decrease, or remain the same after this event? (Assume
the amount of water remains constant in the lock).
This is a problem that Paul Hewitt, in his book, Conceptual Physics,
addresses. I recommend you look at his ancillary to the book, subtitled,
"Next Time Questions" page 19-2 A. It is ISBN 0-201-21448-2, Addison
Wesley Publishers, 1986. It is also in later editions.
