BIO Prevention of Hip Fractures. 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 2.0 m/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) It 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 undergo to reduce its speed from 2.0 m/s to 1.3 m/s? (b) The acceleration you found in part (a) may seem rather large, but to assess its effects on the hip, calculate how long it lasts.

To Merge into the highway you need to increase your speed from 50 km/h to 100 km/h. If your car can accelerate at 4.0 m/s2, what should the minimum length of the ramp be? (report your answer in meters)
Your Answer:
Question 9 options:
1. 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 1.3m/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/s²) does the hip undergo to reduce its speed from 2.0 m s to 1.3m/s (b) The acceleration you
found in part (a) may seem rather large, but to assess its effects on the hip fully, calculate how
long it lasts. Note: convert cm to m first.
