I read that the escape velocity of a body is independent of the direction of projection.
For example, I could throw a ball at $11.2$ km/s velocity horizontally, and it would still leave earth.
I am unable to visualise or understand this. Could someone explain?
Edit: I think I should put my exact problem down more clearly.
At point A: I release the ball. It has horizontal velocity of 11.2 km/s.
From A to B: Gravity acts on the ball. One component slows down the horizontal velocity and one component constantly attracts the ball to earth.
At B: the ball is trying to leave earth with less than escape velocity.
What I realised: B might not be exactly on earth, the ball might have already covered some height.
So right now, I would just like someone to confirm if what I realised is right. (Or correct me.)
