change in velocity of the astronaut will be
Explanation:
It should be solved by law of conservation of linear momentum.
The mass of the astronaut
The mass of the object thrown
The Initial velocity of the astronaut
The Initial velocity of the object
The Final velocity of the astronaut
The Final velocity of the object
By law of conservation of linear momentum.
So change in velocity of the astronaut will be
