Hour Exam II
Inclass Group Problem
John Jacob is a 65 year old man who has experienced some bouts of fainting in the last
month. Today, John was standing in his kitchen when he blacked out and fell on his hip.
He was brought into the small community outpatient clinic describing pain in his hip area.
The X-ray machine is being repaired and you would like to determine if the force of the
floor on the hip at impact would be large enough to fracture the hip bone. If your
calculations suggest that possibility, you could send John to the major area hospital 60
miles away. You take some measurements on the patient and find that he weighs 165
pounds and he is 6 feet 2 inches tall.
What information do you need and what assumptions will you need to make in order to
estimate the force on John's hip? What physics principles will you use to solve this
problem? Outline a procedure that you can use to find the force.
When you have answered the questions above and outlined a problem-solving procedure,
hand this sheet into your instructor and obtain page 2
of this test question.
