An aircraft can fly at a top speed of 600 k m h . What will its speed be if it flies into a head-wind of 100 k m h ? ( A head-wind blows in the opposite direction to the aircraft. )

Given the speed of aircraft = 600 k m h r Speed of head-wind = - 100 k m / h r ( As blowing in opposite direction ) Speed of aircraft if it is flying into head-wind = Speed of aircraft + Speed of head-wind Speed of aircraft if it is flying into head-wind = ( 600 - 100 ) k m h r Speed of aircraft if it is flying into head-wind = 500 k m h r

An aircraft can fly at a top speed of 600 k m h . The pilot directs the aircraft to fly due north at 600 k m h . A side-wind blows at 100 k m h towards the east. What will be the aircraft's resultant velocity ? ( Give both its speed and its direction. )

Given the top speed of the aircraft = A = 600 kmph due North. The side wind velocity = W = 100 kmph due east. Resultant speed can be found from the following diagram using the resultant of vector addition: Resultant speed R 2 = A 2 + W 2 Substituting the given values, we get Resultant S p e e d 2 = 600 2 + 100 2 Or R = 360000 + 10000 = 470000 = 608 . 3 kmph Hence,the resultant Speed = 608 . 3 k m h r
