Falls resulting in hip fractures are a major cause of injury and even death to the elderly. Typically, the hip's speed at impact is about 2.0m/s. If this can be reduced to 1.3 m/s or less, the hip will usually not fracture. One way to do this is by wearing elastic hip pads. A) if a typical pad is 5.0 cm thick and compresses by 2.0 cm during the impact of a fall, what constant acceleration (in m/s^2 and in g's) does the hip under go to reduce its speed from 2.0 m/s to 1.3 m/s? The acceleration that you found in part "a" may seem very large, but to fully understand its effects on the hip, calculate how long it lasts.
