A plane leaves the airport in Galisteo and flies 170km at 68.0 degrees east of north and then changes direction to fly 230 km at 48.0 degrees south of east, and then changes direction to fly 120 mi west, after which it makes an immediate emergency landing in a pasture. When the airport sends out a rescue crew, in which direction and how far should this crew fly to go directly to the plane?

Montréal is 510 km from Toronto, 12 degrees north of east. At an altitude of 9,000 meters, the windspeed is 80 km/h out of the north. For the entire 510 km, the aircraft flies at 9,000 meters at an airspeed of 300 knots. Draw a triangle whose sides represent the velocity vectors that correspond to the groundspeed, airspeed, and windspeed. Determine: (a) the aircraft heading (direction in which the nose of the aircraft points), in degrees from north. (b) the...

A plane flies over the head of Paul, an Earth observer. Treat Earth and the plane as inertial frames. The plane’s speed is v. When the plane is directly overhead, a light signal is emitted from the center of the plane. It is subsequently detected by two observers, Jack in the front of the plane, and Ben in the back of the plane. They both measure the distance to the center of the plane to be d. a. Assume the...

a) An airplane with a wingspan of 105 m flies due north at a location where the downward component of Earth’s magnetic field is 0.750 × 10−4?. There is also a component pointing due north that has a magnitude of 0.560 × 10−4?. If the speed of the plane is 3.05 × 10 2?/?, find the difference in potential between the wingtips and determine which wingtip is positive. b) The primary winding of a transformer has N1=1200 turns, and the...

A rescue plane flies horizontally at a constant speed searching for a disabled boat. When the plane is directly above the boat, the boat's crew blows a loud horn. By the time the plane's sound detector receives the horn's sound, the plane has traveled a distance equal to one-third its altitude above the ocean. Assuming it takes the sound 2.02 s to reach the plane, and taking the speed of sound to be 343 m/s, determine the following. (a) the...
