# Given the following information: Typical bone fracture force; 90KN 50% fatal on head acceleration if 150 g for 4ms & 50g for 6Oms 50% fatal if whole-body pressure exceeds 3.4X 10 exp 5 N/meter squared Starring column distance = 0.3 m Front surface area of whole-body - 0.8 meters squared Head and chest surface area = 0.5 meters squared Consider a 75-kg passenger not wearing a seat belt traveling at 27m/s (60mph) who comes to rest in 0.010 seconds (car hits a brick wall) after striking an unpadded dashboard. Calculate the average force of impact Calculate the average acceleration in units of "g." (How many "g"?) Calculate the average pressure if head and chest hit dashboard For the driver, what average fore is required to Map the driver to avoid hitting the steering wheel? Why are the answer to stop the so driver different than What kind of collision is this? (elastic or inelastic) Why?****
