e) In order to reduce concussion risk, one could reduce the value of vo. Suppose the stopping distance remained d (an oversimplification, but let's use it for now), and vo is cut in half. How much smaller would the acceleration be? Please answer this question without plugging in any numbers! Follow these steps: Step 1) Write out expressions for aslow and afast in terms of d, vo, slow and vo, fast Step 2) Write an equation relating Vo, slow and vo, fast Step 3) Write an expression for the ratio aslow/afast Lots of variable cancellations should happen, allowing you to write a final answer in the form aşlow = [some number] · afast-
