Answer to Question #296858 in Classical Mechanics for Nixon

Question

A man 5 feet tall casts a shadow of 5 feet on the ground. Find the angle of elevation of the sun ?

Answer 1

$\alpha - \text{Angle of elevation}$

$h = 5ft \text{ male height}$

$h = 5ft \text{ shadow length}$

$\tan \alpha=\frac{h}{l}=\frac{5}{5}=1$

$\alpha =\arctan(1) = 45\degree$

$\text{Answer: }45\degree$
