Homework Help: What is the speed with which she lands?

  1. Nov 27, 2007 #1
    A pole-vaulter of mass 60kg vaults to a height of 6.0m before dropping to thick padding placed below to cushion her fall. What is the speed with which she lands?

    -I know it has something to do with momentum, but I dont even know where to begin on this one
