a person looking out the window of a stationary train noticesthat raindrops are falling vertially down at a speed of 6.59 m/srelative to the ground. when the train moves at a constand velocitythe raindrops make an angle of 25 degrees when they move past thewindow, as the drawing shows. How fast is the train moving.
