Question

A car 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

Answer 1

`\theta = tan^(-1)(v)/(u)`

Step-by-step 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

=
`\vec{u}-\vec{v}`

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

where
`\theta = tan^(-1)(v)/(u)`
