A car travels 90 meters due north in 15 seconds. Then the car turns 32° west of north and travels 40 meters. What is the magnitude and direction? what analytical method is most appropriate (and shortest method) for the problem? polygon method b. component method c. parallelogram method d. Law of sines and cosines
B 3. Given the lengths of vectors A, B, and C, and the angle between A and B. Notice that A = B + С. Prove the law of cosines: |C|² = |Ã₁² + |B|² - 2|A||B| Cos 0. Then, show that if A and B are perpendicular, the law of cosines reduces to the familiar Pythagorean theorem.

# 5) Think in three dimensions. Think about what is your coordinate system. What directions are positive and negative in your coordinate system (clearly show how the positive and negative x, y, and z axes relate to North, East, South, and West)? You and your buddy do not have to have the same coordinate system, but the answer will work out the same for this problem. Clearly draw and label your 3D coordinate system A Los Angeles class nuclear submarine deep in the ocean's water rises 50.0 m straight upward in the water, then propels 200.0 m eastward (from west to east), then 100.0 m horizontally to the north. If an enemy Churchill class nuclear submarine started out at the same location as the Los Angeles class submarine and instead rose 100.0 m straight up, propelled 200.0 m westward, and 50.0 m horizontally to the south. What is the magnitude of the distance between the two submarines in the end? Express answer to 3 sig figs.

A jet plane travels towards a ground-based radar dish. Radar locates the jet plane at a distance D = 11 km from the dish, at an angle θ = 46° above horizontal. 1.) What is the jet plane’s horizontal distance, DH in meters, from the radar dish? 2.)What is the jet plane's vertical distance, DV in meters, above the radar dish? 3.)Write an expression for the distance vector, D, in rectangular form in terms of D and θ, in a coordinate system with the dish at the origin and the unit vectors i and j in the horizontal and vertical directions.
