A man is riding on a flatcar traveling at a constant speed of 9.10 (the figure ). He wishes to throw a ball through a stationary hoop 4.90 above the height of his hands in such a manner that the ball will move horizontally as it passes through the hoop. He throws the ball with a speed of 10.8 with respect to himself.
When the ball leaves the man's hands, what is the direction of its velocity relative to the frame of reference of the flatcar?
