You are traveling on an airplane. the velocity of the plane with respect to the air is 140 m/s due east. the velocity of the air with respect to the ground is 31 m/s at an angle of 30° west of due north. 1) what is the speed of the plane with respect to the ground?

127.36 m/s

Explanation:

velocity of plane with respect to air = 140 m/s due east

velocity of air with respect to ground = 31 m/s 30° west of north

Write the velocities in the vector forms

Let velocity of plane with respect to ground is given by vp/g

According to the formula of relative velocities

The magnitude of the velocity of plane with respect to the ground is given by

Thus, the velocity of plane with respect to the ground is given by 127.36 m/s.
