Skills for solving impulse-momentum problems

An impulse of 150 N ^. s stops your head during a car collision. (a) A crash test dummy’s head stops in 0.020 s, when the cheekbone hits the steering wheel. What is the average force that the wheel exerts on the dummy’s cheekbone? (b) Would this crash fracture a human cheekbone (see Problem 52)? (c) What is the shortest impact time that a person could sustain without breaking the bone?
