The altitude of a hang glider is increasing at a rate of 6.75 m/s. At the same time, the shadow of the glider moves along the ground at a speed of 15.0 m/s when the sun is directly overhead. Calculate the magnitude of the glider's velocity.

16.45 m/s

Explanation:

Let y be the vertical distance and x be the horizontal distance

We are given that

The altitude of hang glider increasing at the rate=

The shadow of the glider moves along the ground at speed=

We have to find the magnitude of glider's velocity.

We know that

Magnitude of velocity=

Substitute the values

Hence, the magnitude of glider's velocity=16.45 m/s

the answer would be 32*f
