Assault With The Ball

[wolfen]

Endline Throw in-GJV Team A running of time so A1 throws the ball pretty hard at B1-hits her knee and goes OOB. My question Is there any level of force in this sitch that justifys a foul ? i called OOB on B but was a little uncomfortable with A throwing the ball at B like that . At the extreme could A throw the ball and hit B in the face-doesn't seem right to me .... Thanks for input.
