A woodpeckers brain is specially protected from large
decelerations by tendon-like attachments inside the skull. While
pecking on a tree, the woodpeckers head comes to a stop from an
initial velocity of 0.470 m/s in a distance of only 2.30 mm. Find
the acceleration in m/s2 and in multiples of g (g = 9.80
multiples of g:
calculate the stopping time:
The tendons cradling the brain stretch, making its stopping
distance 5.06 mm (greater than the head and, hence, less
deceleration of the brain). What is the brains deceleration,
expressed in multiples of g?
