You spot a plane that is 1.50 km north, 2.5 km east, and at an altitude 5.0 km above your position. (a) how far from you is the plane? (b) at what angle from due north (in the horizontal plane) are you looking? (c) determine the plane’s position vector (from your location) in terms of the unit vectors, letting be to- ward the east direction, be toward the north direction, and be in vertically upward. (d) at what elevation angle (above the hori- zontal plane of earth) is the airplane?

Imagine you work as a consultant, and your daily job involves listening to the constructive criticism of others. as part of your job, you must listen to opposing viewpoints to make important decisions. in this activity, you are a consulting dam engineer. you must make a decision about four different dams; should they be repaired, taken down, or left alone? you will listen to contrasting opinions about what should be done with the dams before you make the final decision. as the consulting dam engineer, what do you decide to do with this dam? explain your reasoning. by making your decision, did you support the opinions of the mayor and/or the dam safety official? why or why not?
