No chatgpt pls will upvote A woodpecker's brain is specially protected from large decelerations by tendon-like attachments inside the skull. Whilepecking on a tree, the woodpecker's head comes to a stop from an initial velocity of 0.575 m/s in a distance of only 2.10mm.(a) Find the acceleration in m/s² and in multiples of g (g = 9.80 m/s²). (Enter the magnitudes.)in m/s²78720× m/s²in multiples of g8033× 9(b) Calculate the stopping time (in s).0(c) The tendons cradling the brain stretch, making its stopping distance 4.45 mm (greater than the head and, hence, lessdeceleration of the brain). What is the brain's deceleration, expressed in multiples of g? (Enter the magnitude.)3791× 9+

A landscape architect is planning an artificial waterfall in a city park. Water flowing at 1.70 m/s will leave the end of a horizontal channel at the top of a vertical wall h = 2.35 m high, and from there it will fall into a pool (Fig. P3.42). (a) Will the space behind the waterfall be wide enough for a pedestrian walkway? (b) To sell her plan to the city council, the architect wants to build a model to standard scale, which is one-twelfth actual size. How fast should the water flow in the channel in the model?

A pirate has buried his treasure on an island with five trees located at the points (30.0 m, 20.0 m), (60.0 m, 80.0 m), (10.0 m, 10.0 m), (40.0 m, 30.0 m), and (70.0 m, 60.0 m), all measured relative to some origin, as shown in Figure P1.69. His ships log instructs you to start at tree A and move toward tree B, but to cover only one-half the distance between A and B. Then move toward tree C, covering one-third the distance between your current location and C. Next move toward tree D, covering one-fourth the distance between where you are and D. Finally move toward tree E, covering one-fifth the distance between you and E, stop, and dig. (a) Assume you have correctly determined the order in which the pirate labeled the trees as A, B, C, D, and E as shown in the figure. What are the coordinates of the point where his treasure is buried? (b) What If? What if you do not really know the way the pirate labeled the trees? What would happen to the answer if you rearranged the order of the trees, for instance, to B (30 m, 20 m), A (60 m, 80 m), E (10 m, 10 m), C (40 m, 30 m), and D (70 m, 60 m)? State reasoning to show that the answer does not depend on the order in which the trees are labeled. Figure 1.69
