Given:
Speed of the wind that is blowing in the north direction = 5 km/hr
Speed of the airplane that is moving in the east direction = 200km/ 40hr
To find:
Velocity of the airplane with respect to the wind.
Solution:
The velocity of wind = 5 km/hr j
Velocity of airplane = 200km/ 40 hr i = 5 km/hr i
Velocity of airplane with respect to the wind:
= velocity of airplane - velocity of wind.
= 5 km/hr i - 5 km/hr j
= 5 (i - j) km/hr
Therefore the velocity of the airplane with respect to the wind = 5(i -j) km/hr.
