A person looking out the window of a stationary train notices that raindrops are falling vertically down at a speed of 6.6 m/s relative to the ground. When the train moves at a constant velocity, the raindrops make an angle of θ = 36° when they move past the window as the drawing shows. How fast is the train moving?
