The compass on an airplane indicates it is headed due east, and the airspeed

indicator shows it is moving through the air at 450

km/hr

. The wind is blowing 120

km/hr

in

a direction 30° south of east.

(a) What is the velocity of the airplane rel

ative to the earth?

(b) In what direction should the pilot head for the plane to travel due east? What will be the

airplane velocity relative to the earth?

Please explain to second part preciely

thank you

A light plane attains an airspeed of 500 km/h. The pilot sets out for a destination 780 km due north but discovers that the plane must be headed 19.0° east of due north to fly there directly. The plane arrives in 2.00 h. What were the (a) magnitude and (b) direction of the wind velocity? Give the direction as an angle relative to due west, where north of west is a positive angle, and south of west is a negative...

4. A pilot flying from Honolulu to California flies at an airspeed of 300.0 m/s (“airspeed” = airplane’s speed through the surrounding air) with her airplane pointed 70.0˚ to the east of north. However, the air itself is moving with a 50.0-m/s windspeed blowing due east. When the pilot adds together the two vectors of her airspeed and the windspeed, she gets her groundspeed: the airplane’s actual velocity relative to the ground below. (Even though these are called “speeds” by...

Instruments in airplane A indicate that, with respect to the air, the plane is headed 30° north of east with an air speed of 460.00 mi/h. At the same time, radar on ship B indicates that the relative velocity of the plane with respect to the ship is 360.00 mi/h in the direction 33° north of east. Given, the ship is steaming due south at 12 mi/h. Determine the velocity of the airplane. (Round the final answer to two decimal...
