No. You can have one foot on the ground or no feet on the ground as long as the player has secured the ball. ie. A player can signal for a timeout in mid-air as long as he/she has secured the ball and signaled for the timeout before stepping out of bounds.
The ball would take approximately 4 seconds to hit the ground, neglecting air resistance. This calculation is based on the constant acceleration due to gravity (9.8 m/s²), assuming the ball is dropped and not thrown.
Yes, as long as you do not disturb the ball.
The shaddow would be 6.7 feet long (assuming flat ground)
Yes, a ball carrier can have their hand touch the ground while still being considered upright and not down, as long as any part of their body other than their feet is touching the ground and they are not in contact with the ground in a way that would declare them down. This is often seen when a player falls and uses their hand to break the fall, allowing them to continue running. The key factor is that the player must not be down by contact with the ground.
If the player holds on to the ball and it is determined that it did not touch the ground, it is an out. If the player drops the ball while falling over the fence, it is a home run. Added: To get more technical, I think as long as the fielder has his feet inside the area of the field of play, it would be an out. If the entire body (including feet) are over the fence when the catch is made, then it would be a home run. The above answer is wrong. If a fielder leaps and catches the ball before he touches dead ball territory the catch is good and the batter is out. It doesn't matter where he is in relation to the fence. He could be ten feet into dead ball territory and as long as he hasn't touched the ground, the catch is valid.
A long time...
12 feet
As long as you don't touch the net, and the ball doesn't touch the ground, yes.
A foot ball feild
By the Way, guys, this is based on the equation H= -16t2+vt+s
As long as the ball does not touch the ground or a wall, the batter is called out.
