A woodpecker's brain is protected from high accelerations, and thus large forces, by tendon-like attachments inside the skull. While pecking on a tree, a woodpecker's head comes to a stop from an initial speed of 0.62 m/s in a distance of only 1.5 mm. Part A: Assuming contact acceleration, find the magnitude of its head's acceleration in multiples of g (g=9.90 m/s^2). Part B: Calculate the stopping time of the woodpecker's head, in seconds. Part C: The tendons cradling the woodpecker's brain stretch, making the brain's stopping distance 4.4 mm which is greater than the head's stopping distance. That results in a lower magnitude of acceleration for the brain. What is the magnitude of the brain's acceleration, expressed in multiples of g
