Answer:Zero
Explanation:
Given
mass of ball [tex]m=10\ kg[/tex]
If the ball is thrown upward then at maximum point velocity of ball is zero because ball is no longer able to move upward
Momentum(P) of a particle is given by
[tex]P=mass\times velocity[/tex]
[tex]P=10\times 0[/tex]
[tex]P=0[/tex]
Therefore at the highest point momentum is zero .
