5. An aeroplane intends to fly to a city that is 200 km due north of its current location. The plane can fly at 250 km/h in still air. A 100 km/h wind is blowing to the north west direction. The pilot forgets to take into account the wind and he heads due north. The pilot estimates his travel time without considering the wind. What is this time? Give your answer in hours. b) In what direction does the plane...
The pilot of an aircraft wishes to fly due west in a 54-km/h wind blowing toward the south. If the speed of the aircraft relative to the air is 177 km/h, (a) in what direction (degrees north of west) should the aircraft head, and (b) what will be its speed (km/h) relative to the ground? Caution: The speed relative to the air is not the same as the speed relative to the ground. The pilot wishes to fly due west...
A plane takes off and climbs to 3 000 m in five minutes at an angle of 8.28 degrees. When it reaches 3 000 m, the plane levels out and adjusts to its constant cruising speed of 500 km/h. At this height, there is a wind (a "jet stream") blowing at 100 km/h 30 degrees East of North. a) What is the magnitude of the plane's acceleration during the first five minutes of the flight? b) After reaching its cruising...
The pilot of an aircraft wishes to fly due west in a 41.0 km/h wind blowing toward the south. The speed of the aircraft relative to the air is 225 km/h. (a) In what direction should the aircraft head? (b)What will be its speed relative to the ground?
Constants Part A An airplane pilot wishes to fly due west. A wind of 84.0 km/h is blowing toward the south ' the airspood of the plane Ots speed in sti. air) is 400.0 km/h . in which direction should the pilot head? Express your answer as an angle measured north of west north of west Submit Request Answer Part B What is the speed of the plane over the ground? km/h Submit Request Answer Provide Feedback
The magnitude of a velocity vector is called speed.
Suppose that a wind is blowing from the direction N45°W at a speed
of 50 km/h. (This means that the direction from which the wind
blows is 45° west of the northerly direction.) A pilot is steering
a plane in the direction N60°E at an airspeed (speed in still air)
of 100 km/h. The true course, or track, of the
plane is the direction of the resultant of the velocity vectors...
An airplane pilot wishes to fly due west. A wind of 72.0 km/hkm/h is blowing toward the south. Part A If the airspeed of the plane (its speed in still air) is 335.0 km/hkm/h, in which direction should the pilot head? Express your answer in degrees. Part B What is the speed of the plane over the ground? Express your answer in kilometers per hour.
The captain of a plane wishes to proceed due west. The cruising speed of the plane is 235 m/s relative to the air. A weather report indicates that a 34.6-m/s wind is blowing from the south to the north. In what direction, measured with respect to due west, should the pilot head the plane? degrees Select of west
A plane with air speed of 620 km/h is supposed to fly iin the direction of 27 degrees north of east. A wind is blowing from east at a speed of 110 km/h. In what direction should the pilot head the plane?
Consider an airplane that has an air speed of 120 km/hr flying with its nose pointing north with a 90 km/hr cross-wind blowing from the west. Show that the ground speed of the airplane is 150 km/hr. In what direction is the net result of the plane’s vector pointing?
