The pole vault landing pad at an Olympic competition contains
what is essentially a bag of air that compresses from its "resting"
height of 1.4 m down to 0.3 m as the vaulter is slowed to a stop.
(a) What is the time interval during which a vaulter who has just
cleared a height of 7.0 m slows to a stop?
(b)What is the time interval if instead the vaulter is brought to
rest by a 19.2-cm layer of sawdust that compresses to 5.1 cm when
he lands?
(c) Qualitatively discuss the difference in average force the
vaulter experiences from the two different landing pads. That is,
which landing pad would exert the least force on the vaulter and
why?
