Answer:

one tenth of the velocity of the ball.

Explanation:

Recoil velocity is the velocity at which a person's body moves when he fires a bullet or an object  with a particular mass and speed. The following formular is used to calculate recoil velocity.

mv = MV.....................equation 1

where:

  • m is mass of object shot or tossed
  • v is the velocity of object fired or tossed
  • M is mass of person firing the object
  • V is the recoil velocity of the person firing the object

From the question we know that  [tex]m= 1/10M[/tex] . so we substitute this into equation 1. we get;

[tex]1/10M*v =MV[/tex]

[tex]1/10v=V[/tex]

therefore your recoil velocity will be one tenth the velocity of the ball
