Question
A woodpecker's brain is specially protected from large decelerations by tendon-ke attachments inside the skull. While pecking on a tree, the woodpecker's head comes to a stop brom an
initial velocity of 0.535 m/s in a distance of only 2.15 mm.
(a) Find the acceleration in m/s² and in multiples of g (g=9.80 mys). (Enter the magnitudes)
in m/s2
in multiples of g
x m/s²
x 9
93.77
95
(b) Calculate the stopping time (in s).
(c) The tendons crading the brain stretch, making its stopping distance 4.30 mm (greater than the head and, hence, less deceleration of the brain). What is the brain's deceleration,
expressed in multiples of g? (Enter the magnitude.)
