The head injury criterion (HIC) is used to assess the likelihood of head injuries arising from various types of collisions; an HIC greater than about 1000 s is likely to result in severe injuries or even death. The criterion can be written as HIC=(aavg/g)^2.5Δt, where aavg is the average acceleration during the time Δt that the head is being accelerated, and g is the free-fall acceleration. The figure shows a simplified graph of the net force on a crash dummy's 4.5 kg head as it hits the airbag during a automobile collision. What is the HIC in this collision? Give your answer in seconds.
