A car travels due east with a speed of 60.0 km/h. Rain is falling vertically with respect to the Earth. The traces of the rain on the side windows of the car make an angle of 45.0° with the vertical. Find the velocity of the rain with respect to the car and with respect to the Earth?
Vrain with respect to earth AND car = 60 km/h.
The car's horizontal motion does not affect the vertical velocity component.
Equal vertical and horizontal velocity components with respect to the car make the rain tracks 45 degrees on the side windows.

because you are insane
