Professional Application: A woodpecker’s brain is specially protected from large decelerations by tendon-like attachments inside the skull. While pecking on a tree, the woodpecker’s head comes to a stop from an initial velocity of 0.600 m/s in a distance of only 2.00 mm. (a) Find the acceleration in and in m/s multiples of g (g = 9.80 m/s). (b) Calculate the stopping time. (c) The tendons cradling the brain stretch, making its stopping distance 4.50 mm (greater than the head and, hence, less deceleration of the brain). What is the brain’s deceleration, expressed in multiples of ?

In attempting to pass the puck to a teammate, a hockey player gives it an initial speed of 1.91 m/s. However, this speed is inadequate to compensate for the kinetic friction between the puck and the ice. As a result, the puck travels only one-half the distance between the players before sliding to a halt. What minimum initial speed should the puck have been given so that it reached the teammate, assuming that the same force of kinetic friction acted on the puck everywhere between the two players?
You are driving along a straight section of road at 13 m/s when 10 m in front of you a furry creature jumps out into the middle of the road. You instantly slam on your breaks, but the breaks lock so that you slide along the pavement with kinetic coefficient of friction between the tires and the pavement of 0.65. By what distance do you stop short of running over the furry creature or by what distance is your roadkill dinner behind you when your car finally comes to a halt? Note that the total mass of the car (including you) is 1360 kg, while the mass of the furry creature is 2.6 kg.
