A football quarterback is moving straight backwards at a speed of 2.00 m/s when he throws a pass to a player 18.0 m straight downfield. If the ball is thrown at an angle of 25.00 relative to the ground and is caught at the same height as it is released, what is its initial speed (m/s) relative to the ground? (Note: the player’s backward motion will not be a factor in this problem.)
