Question

a stationary person observes that rain is falling vertically downwards at 30km/hr.A cyclist is moving on the level road at 10km/hr . In what direction should rhe cyclist hold his umbrella to protect himself from rain?​

Answer 1

Answer:

the answer might be

${ \tan}^{ - 1} (3) = theta$

whenever we switch from the ground reference to the person's reference we add the velocity of the person in opposite direction and then calculate the angle.

but remember that the theta I find is with the horizontal you can find it with vertical too.

hope it's help have a nice day or night
