Answer:
The velocity of astronaut will be 0.105 m/s in opposite direction of the tool.
Explanation:
Given that,
Mass of the Astronaut, m = 68.5 kg
Mass of the the tool, m' = 2.25 kg
Speed of tool, v' = -3.2 m/s (direction is sway from space station)
It is required to find the speed of the astronaut. The momentum will remain conserved. So,

v is the speed if Astronaut

So, the velocity of astronaut will be 0.105 m/s in opposite direction of the tool.
