The altitude of a hang glider is increasing at a rate of 6.55 m/s. at the same time, the shadow of the glider moves along the ground at a speed of 15.5 m/s when the sun is directly overhead. find the magnitude of the glider's velocity.

v = 16.82 m/s                      

Explanation:

It is given that,

The altitude of a hang glider is increasing at a rate of 6.55 m/s,

The shadow of the glider moves along the ground at a speed of 15.5 m/s,

Here, the horizontal velocity is v₁ and the vertical velocity is v₂. Let v is the magnitude of glider's velocity. It can be calculated as :

v = 16.82 m/s

So, the magnitude of the glider's velocity is 16.82 m/s. Hence, this is the required solution.

the answer is b ) square root of 5
