# Constant speed and velocity

A car travels due east with a speed of 50.0 km/h. Raindrops are falling at a constant speed 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 following reference frames.
(a) the car _____m/s

(b) the Earth ____ m/s

Any help would be greatly appreciated!
