1)Homework Statement
An astronaut of mass 82.0 kg is taking a space walk to work on the International Space Station. Because of a malfunction with the booster rockets on his spacesuit, he finds himself drifting away from the station with a constant speed of 0.600 m/s. With the booster rockets no longer working, the only way for him to return to the station is to throw the 7.20 kg wrench he is holding.
1)In which direction should he throw the wrench?
-Away from the station
-Towards the station
2)He throws the wrench with speed 18.58 m/s with respect to himself.
After he throws the wrench, how fast is the astronaut drifting toward the space station?
3)What is the speed of the wrench with respect to the space station?
3Your answer is incorrect.
MV = mv
The answer to the first question is that he should throw it away from the space station.
For the second I tried doing (V)*(82) = (7.2)(18.85), for V= 1.66 m/s but this is incorrect.
For the third, I would think that it would be 18.85-0.600 = 18.25 m/s but this is also incorrect according to the system that I'm entering this answers into.
