A car travels due east with a speed
of 36.0 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 42.0° with the vertical. Find the velocity of the rain
with respect to the car and the earth. (Enter the magnitude of the
velocity.)
(a) the car km/h
(b) the Earth
