A bird is migrating non-stop at a distance of 2000 km. Its destination is due south of its present position. In still air, the bird can fly with a speed of 40 km/h. However, there is a wind of 25 km/h from the west. a) In order to make the trip following a straight-line path, in what direction should the bird head? b) How long will the trip take?

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...

A pilot must fly a plane due north (90 degrees) to reach a destination. The plane can fly at 323 km/h in still air. A wind is blowing out of the northeast (225 degrees) at 40 km/h. What is the speed of the plane relative to the ground? The pilot must point the plane to the east of north in order to compensate for the wind speed.

An airplane takes off and heads for a destination that is 673 km away in a direction 72.0° North of West. In order to avoid a storms, the airplane initially flies 128 km at 7.0° East of North before changing direction and heading straight to the final destination. How far and in which direction should the airplane fly during the second leg of its trip in order to reach its final destination safely?

Canadian geese migrate essentially along a north-south direction for well over a thousand kilometers in some cases, traveling at speeds up to about 100 km/h. One such bird is flying at 100 km/h relative to the air, but there is a 30.0 km/h wind blowing from west to east. PART A : At what angle relative to the north-south direction should this bird head so that it will be traveling directly southward relative to the ground? PART B: How long...

An airplane is heading due south at a speed of 662 km/h . A wind begins blowing from the southwest at a speed of 80 km/h (average). In what direction should the pilot aim the plane so that it will fly due south? Express your answer to three significant figures and include the appropriate units.

An airplane is heading due south at a speed of 688 km/h If a wind begins blowing from the southwest at a speed of 90 km/h (average), calculate: (a) the velocity (magnitude and direction) of the plane relative to the ground, and (b) how far from its intended position will it be after 11.0 min if the pilot takes no corrective action. [Hint: First draw a diagram.] (a) VP,G = 628 km/h (b) Dx = 16.5 km  these are the answers...

A bird travels from island A to island B flying in a straight horizontal line. The distance between the two islands is 1 km. When there is no wind, the bird usually spends 2.50 kcal of energy for flapping its wings to create lift and move forward for the whole trip. Unfortunately, during the trip, a cold wind is present and induce a drag force on the bird of 35N, against the direction of motion. In addition, the temperature of...

1. A baseball thrown at an angle of 65.0 ∘ above the horizontal strikes a building 18.0 m away at a point 8.00 m above the point from which it is thrown. Ignore air resistance. A) Find the magnitude of the initial velocity of the baseball (the velocity with which the baseball is thrown). I got 17.0 m/s B) Find the magnitude of the velocity of the baseball just before it strikes the building. C)Find the direction of the velocity...

An airplane heads due west at a speed 150 km/h relative to the wind. If the wind is moving at 30 km/h toward the north, what is the speed of the airplane relative to the ground? A jet airliner moving initially at 300 mi/h due east enters a region where the wind is blowing at 100 mi/h in a direction 30◦ north of east. What is the speed of the aircraft relative to the ground? A certain river is 0.5...
