Freethrows

[ilya]

Ok. I have 3 questions about free throws:
1) Can a player have the ball for more than 10 seconds? Say, he's standing on FT line bouncing it for 9 seconds and then for 3 seconds he's getting ready for a shot. I've read the rules and it's a violation, yet they NEVER call that.
2) Can i cross FT line? I often shoot and go over the line by accident (lose balance or something) and i don't know if that should be called a violation.
3) Can i jump while shooting FT if i don't cross the FT line?
Thanks in advance.
