Person A is running North at 5 m/s and Person B is running North at 8 m/s parallel to the y axis. The paths of person A and person B have a horizontal distance (along the x axis) of 10 feet between them. Person A can throw a ball at 20 m/s. What angle does person A need to throw the ball relative to the axes so that person B catches the ball? At the instant that Person A throws the ball, how far behind or ahead of Person A does Person B need to be?
