- An airplane takes off from a runway at an angle of 15⁰. A fence is 50 feet from the location where the plane took off from the runway. What is the altitude of the airplane when it passes over the fence? (Please detail it so I can understand for future problems that is similar)2. An airplane flying N30° W at 150 km/h encounters a wind blowing E5 N at 40 km/h. Determine the resultant ground velocity of the plane. Include a vector diagram in your solution.6. If a river has a westward current of 2.30 m/s and you head due north across the river on a boat that has a speed of 3.5 m/s in still water, then what is speed of the boat relative to the shore? At what angle does it cross the river? Draw a picture and label the angle.
- 17. For a projectile, the y-axis motion occurs as a result of the gravitational action on the projectile and this gives way to its fall toward the Earth in parabolic motion. a. True b. False 18. The sum of two or more vectors is called a complementary vector a. True b. False3. It is September of 1936, and the Kenyan aviatrix Beryl Markham is attempting the first solo flight of the Atlantic from east to west in a specially outfitted Vega Gull, against the prevailing winds of the North Atlantic jet stream. Her plan is to fly from London to New York, proving the potential for commercial airline routes. Her initial heading (direction she points the nose of the plane) is 288 degrees. Note, in navigation, directions are measured clockwise from north At 10,000 feet, the winds are going southwesterly at 235 degrees with wind velocity of about 50 knots. The Vega Gull flies at a top airspeed of 150 knots (relative to still air). What direction is she flying relative to the ground? What will be the plane's groundspeed, i.e., the plane's speed relative to the ground?3. A flock of ducks is trying to migrate south for the winter, but they keep being blown off course by a wind blowing from the west at 14 m/sm/s . A wise elder duck finally realizes that the solution is to fly at an angle to the wind. If the ducks can fly at 15 m/s relative to the air, in what direction should they head in order to move directly south? Please answer in degrees west of south
