The cushion on which a pole vaulter lands after their vault is essentially a cushion of air with a normal height of 1.2 m, which is compressed to about 0.20 m when the vaulter comes to rest on it. a) In what time is a jumper who has just crossed the bar at 6.40 m stopped until he comes to a standstill? b) How long would the period be if instead of using an air cushion you would use a 20 cm thick layer of sawdust that compresses to 5.0 cm on impact? c) Discuss qualitatively how the mean forces on the jumper differ for these two landing mats. In other words, which of the mats exerts the lesser force on the jumper and why?
