If one child doesn't cash the ball and it flies out the window and what direction does the ball fly? (ignoring wind resistance)

Question

two children are throwing a ball back and forth straight across the back seat of a car . the ball is being thrown 6 mph related to the car and the car is traveling 25 mph down the road

= ________degrees measured relative to the cars forward Direction

Answer 1

I think the answer depends on the size, shape and distance away from the window.

If the window is round and the size of the ball, then the angle is exactly 90 degrees relative to the car's forward Direction.

Don't see how the velocity of the ball nor the car matters since the velocities are the same until the ball is thrown.

If the back window of the car is missing, the angle could be 180 degrees relative to .....

The angle also depends upon how far from the open window the ball is when thrown.

There are too many variables to get an finite answer, but it is a problem that requires boundaries in order to obtain answers.
