JC-6) Pole in Barn Paradox
A pole-vaulter holds a 16 ft pole. A barn has doors a both ends, 10.0 ft apart. The pole-vaulter on the
outside of the barn begins running toward one of the open barn doors, holding the pole level in the
direction he is running. When passing through the barn, the pole fits (barely) entirely within the barn all
at once.
How fast is the pole-vaulter running?
a)
b) According to whom -- the pole vaulter or an observer stationary in the barn --
does the pole fit in all at once? Explain your answer.
c) According to the pole vaulter, which occurs first, the front end of the pole leaving
the barn or the back end of the pole entering the barn? Justify your answer by calculating the
time interval between the two events.
