In outer space no other force like gravity and friction are nevertheless. The astronaut's final speed with respect to the shuttle after the tank is thrown is 1.9 m/s.

The formula,

Where,
- mass first object = 63.0 kg
- mass ( second object) = 10.0 kg
- Velocity of the first object = ?
- Velocity of the second object = 12.0 m/s
Put the value in the formula,
63 x v1 = 12 x 10
V2 = 1.9m/s

The astronaut's final speed with respect to the shuttle after the tank is thrown is 1.9 m/s
