Answer: Yes
Explanation:
Yes, it is possible for a player to kick the ball over the net without the penalty, and for example in some sports such as football, there must be a penalty for kicking the ball in the goal, and for that, the player needs a little bit of time and that is why all of the players are waiting for that penalty to be done.
This thing is possible for volleyball players, they can kick the ball over the net without it.
