Falls resulting in hip fractures are a major cause of injury andeven death to the elderly. Typically, the hipâs speed at impact isabout 2.0m/s . If this can be reduced to 1.3m/s or less, the hipwill usually not fracture. One way to do this is by wearing elastichip pads.
1.If a typical pad is 5.0cm thick and compresses by 2.0cm duringthe impact of a fall, what acceleration (in m/s^2) does the hipundergo to reduce its speed to 1.3m/s ? a=? m/s^2
2.What acceleration (in g's ) does the hip undergo to reduce itsspeed to 1.3m/s ? a=?g
3.The acceleration you found in part A may seem like a rather largeacceleration, but to fully assess its effects on the hip, calculatehow long it lasts. t=?s
