Question

trigonometry question. ​

Answer 1

The velocity of the plane is along the 30° with the horizontal.

Now, we know that velocity is a vector quantity and can be broken down into components into sin and cos in vertical and horizontal direction respectively.

Thus, Vertically, Velocity of the plane will be Total velocity * sin theta = 180 km /h * sin 30°

Thus, Velocity in vertical direction of the plane = 90 km/h

Thus, to attain a height of 9 km at the speed of 90 km/h in vertical direction it'll take 0.1 hour = 6 minutes.
