The velocity of an airplane with respect to the ground is 200 m/s at an angle of 30 degrees NORTH of EAST. The velocity of the airplane with respect to the air is 150 m/s at an angle of 60 degrees NORTH of EAST. What is the velocity of the air with respect to the ground?

  • physics -

    Wind speed vector + Air speed vector = Ground speed vector

    Perform the vector subtraction.

    Wind speed = Ground speed - Air speed

    North component of wind speed
    = 200 sin30 -150 sin60 = ?

    East component of wind speed
    = 200 cos30 -150 cos60 = ?

  • physics -

    yep and then you do the sqrt( -29.9^2 +98.2^2) to get the velocity
