Question

The altitude of a hang glider is increasing at a rate of 7.35 m/s. At the same time, the shadow of the glider moves along the ground at a speed of 14.5 m/s when the sun is directly overhead. Find the magnitude of the glider's velocity.

Answer 1

v=sqrt[v(x)²+v(y)²]=
=sqrt[7.35²+14.5²]=16.26 m/s
