If it takes the bird 15 min to travel 5.8 km relative to the Earth, what is the velocity of the wind, in meters per second, relative to the Earth? Take the direction of travel of the seagull to be positive.

Incomplete question.The complete question is here

A seagull can fly at a velocity of 9.00 m/s in still air.If it takes the bird 15 min to travel 5.8 km relative to the Earth, what is the velocity of the wind, in meters per second, relative to the Earth? Take the direction of travel of the seagull to be positive.

Explanation:

Given data

The velocity of bird:

Assume that:

The bird feels the air stream is equal in opposite direction  or:

According to the relative motion concept the velocity of wind VAE is given by:

answer; i believe that the correct answer is (d) a very small amount of mass

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
