Acar is moving in a straight line with velocity v. raindrops are falling vertically downward with a terminal velocity u. at what angle does the driver think the drops are hitting the windshield? explain

Explanation:

A car is moving in straight line with velocity v

raindrop is falling vertically downwards with velocity u

to find the angle at which rain drop is hitting the windshield

the driver will see the rainfall velocity relative to the moving car

∴ The apparent velocity will be

                =

Rain will be falling on wind shield  at  an angle θ .
