Golf Pull the Pin

בערך

The task is like in golf - to throw the ball into the hole, but not one, but all that are in a place bounded by hairpins. The balls are black, and they need to be repainted red. To do this, you need to pull out the pin so that the red ball connects with the black ones and repaints them. Next, the most interesting thing is that in order to move the pins you have to hit them with the ball, which is located at the bottom near the hole. This is the hardest part. Calculate the correct stroke to push that flap back. Which you need, and not the one that you accidentally get in the Golf Pull Pin game.
