Question

A jet is flying due north relative to the ground. The speed of the jet relative to the ground is 155 m/s. The wind at the jet’s altitude is 40.0 m/s toward the northeast (45.0∘∘ north of east). Suppose that the +x-axis is directed eastward and the +y-axis is directed northward. Find the speed of the jet relative to the air (its airspeed). Find the direction in which the pilot of the jet must point the plane so that it travels due north relative to the ground. The direction angle is measured from the +x-axis toward the +y-axis.

Answer #1

An aircraft wishes to travel due east, and must compensate for a
45.0 m/s wind in the northerly direction. If the airspeed of the
plane is 120 m/s , what will be the (Eastward) groundspeed in the
scenario?
If the pilot wishes to travel due east , how must the aircraft
be directed?

An airplane flies due north with an air speed of260 km/h . A
steady wind at 65 km/h blows eastward. (Air speed is the speed
relative to the air.)
What is the plane’s ground speed (vpg)?
If the pilot wants to fly due north, what should his heading
be?

A pilot must fly his plane due north to reach his destination.
The plane can fly at 300 km/h in still air. A wind is blowing out
of the northeast at 90 km/h.
(a) What is the speed of the plane relative to the ground?
(b) In what direction must the pilot head his plane to fly due
north?

A passenger on a moving train walks at a speed of 1.50 m/s due
north relative to the train. The passenger's speed with respect to
the ground is 4.5 m/s at an angle of 31.0°west of north. What are
the magnitude and direction of the velocity of the train relative
to the ground?

A high altitude jet airplane has a velocity relative to the air
of 320 m/s due west. At a certain moment, the pilot notices a
mountain peak directly west of
the plane at a horizontal distance of 4.20 km. 10 s later, the
peak is observed to be a horizontal distance 4.18 km away in a
direction 17?north of west.
(a) Set up a coordinate system and given the components of the
displacement
vectors between the airplane and the mountain...

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 ultralight aircraft is flying at 5.00 m/s in the direction
40o north of west, relative to the air. The wind’s velocity is 3.00
m/s in the direction due west (with respect to the ground). What is
the ultralight’s velocity with respect to the ground?

A 362-kg boat is sailing 17.0° north of east at a speed of 1.60
m/s. 40.0 s later, it is sailing 40.0° north of east at a speed of
4.40 m/s. During this time, three forces act on the boat: a 30.5-N
force directed 17.0° north of east (due to an auxiliary engine), a
23.8-N force directed 17.0° south of west (resistance due to the
water), and (due to the wind). Find the (a) the magnitude and (b)
direction of...

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...

An
aircraft has a cruising speed of 100m/s. On this particular day,
wind id blowing toward the east at 75.0m/s.
a) If the plane pointed due north, what is the
magnitude&direction of the velocity relative to the
ground?
b) If pilot wishes the plane to travel due north, determine
the direction the plane should initially be pointed. Could you
please include the degree and direction like [W of N]?
c) If the plane travelled due north as shown in part...
