I am continuing this question to this one as a new one in order to not post to many questions under one title.
On the wiki page about Coriolis force there is a picture to help demonstrate the concept:
The blue dot located at the most bottom point is the thrower.
The non-inertial reference frame (left) shows the ball curving to the right, due to the Coriolis force. The thrower is here the observer.
In the inertial reference frame, some other observer howering above the carousel, sees the ball follow a straight path until it reaches the center of the carousel.
I will draw a picture:
In my picture, the red curve is the path that the thrower will see.
My question:
I am interested when we are some looking the carousel from up and we are stationary.
I am interested why will the observer howering above the ground (say some drone) see the ball go to the centre of the rotation (as shown in the right wikipedia picture), if the ball (and the thrower) have before the throw some tangential velocity component (the horizontal green vector) and when the thrower throws it he adds the velocity component to the y axis, but still the resultant velocity vector should be the green vector $\mathbf v_{res}$ in my picture, and is pointing to some 45 degrees and not directly to the centre. Why will the ball go straight to the centre and not like that green vector?
