I have this kid throwing a ball with mass M and from high H.
He is trying to hit a crack in the floor.
I need to show that in order for the ball not to miss the crack, the minimal width of the crack (delta x) should be the expression in the red box in the pic.
I wrote down about everything I know about the Uncertainty principle...
How can I find the connection between (delta v) and v?
