An airplane leaves from city A, located in the east 1500 km from city B. The aircraft has a speed of 500km/h to the east and at the same time it blows a wind of 100km/h from the northeast.
a)
In which direction must the course be adjusted so that the
direction of the aircraft is due east to the ground?
b)
How long does it take to get to city B?
c)
Answear question a and b again, but this time the wind comes from
northwest.
In order to move towards the East, we have to change the direction with some angle. Let's say Theta.
Now, if the plane has to move along East, the components of velocity perpendicular to it should vanish. So, this theta must be between East and North-East.
