a. A pole-vaulter of mass 65.4 kg vaults to a height of 5.77 m before dropping to thick padding placed below to cushion her fall. Find the speed with which she lands?

b. If the padding brings her to a stop in a time of 0.485 s, what is the average force on her body due to the padding during that time interval?
