1) How long does it take for the ball to hit the ground?

2) What was the initial speed of the ball when it was thrown from balocny?

3) Let θ be the impact angle between the ball's velocity vector and the ground just before the ball strikes the ground as shpw bleow , consider the case where the boy thows the ball with the same horizontal velocity expression correctly relates the impact angle for the case of the taller balcony to the impact angle for the original balcony?
