A woodpeckers brain is specially protected from large decelerations by tendon-like attachments inside the skull. While pecking a tree, the woodpeckers head comes to a stop from an inital velocity of 1 m/s in only 1.5 mm. A) Find the acceleration of the woodpeckers head. B) The tendons cradling the brain stretch, increaing the stopping distance for the brain to 5 mm. What is the brain's acceleration? C) A woodpecker's brain has a mass of about 2 g. What force is exerted on the tendons holding the brain and how does it compare to a 170 g woodpecker's body weight?
