Question

Snow is falling vertically at a constant speed of 7.3 m/s. At what angle from the vertical do the snowflakes appear to be falling as viewed by the driver of a car traveling on a straight, level road with a speed of 60 km/h?

Answer 1

Answer:

23.7°

Explanation:

Uy = 7.3 m/s

Ux = 60 km/h = 16.67 m/s

$\tan \alpha = \frac{7.3}{16.67} \\ \alpha = \cot( \frac{7.3}{16.67} )$

= 23.7°
