Ornithologists have determined that some species of birds tend to avoid flights over large bodies of water during daylight hours. It is believed that more energy is required to fly over water than land because air generally rises over land and falls over water during the day. (i) A bird with these tendencies is released from an island that is 3 km from the nearest point B on a straight shoreline, flies to a point C on the shoreline, and then flies along the shoreline to its nesting area D. Points B and D are 10 km apart. Assume that the bird instinctively chooses a path that will minimize its energy expenditure. (Round your answers to two decimal places.) (a) In general, if it takes 1.2 times as much energy to fly over water as land, to what point C should the bird fly in order to minimize the total energy expended in returning to its nesting area? km from B (b) Let W and L denote the energy (in joules) per kilometer flown over water and land, respectively. Assuming the bird's energy expenditure is minimized, determine a function for the ratio WL in terms of x, the distance from B to C. W/L = (c) What should the value of W/L be in order for the bird to fly directly to its nesting area D? (d) If the ornithologists observe that birds of a certain species reach the shore at a point 2 km from B, how many times more energy does it take a bird to fly over water than land?

Starting from rest, a 58.0 kg woman jumps down to the floor from a height of 0.560 m, and immediately jumps back up into the air. While she is in contact with the ground during the time interval 0 < t < 0.800 s, the force she exerts on the floor can be modeled using the function F = 9,200 t − 11,500 t2 where F is in newtons and t is in seconds. (a) What impulse (in N⋅s) did the woman receive from the floor? (Enter the magnitude. Round your answer to at least three significant figures.) N⋅s (b) With what speed (in m/s ) did she reach the floor? (Round your answer to at least three significant figures.) m/s (c) With what speed (in m/s ) did she leave it? (Round your answer to at least three significant figures. ) m/s (d) To what height (in m) did she jump upon leaving the floor? m
