Answer:
266.66
Explanation:
and you divide 4000 by 15 to get your answer
Answer: 300 s
Explanation:
The momentum 
is given by the following equation:
Where 
is the mass of the object and 
is the velocity.
In addition, according to the conservation of linear momentum, we have:
(1)
Where:
is the initial momentum of the astronaut, which is initially at rest
is the final momentum, being 
, 
and 
Then (1) is rewritten as:
(2)
Finding te velocity of the astronaut 
:
(3)
(4)
(5) The negative sign of the velocity indicates it is directed towards the spaceship, however its speed (the magnitude of the velocity vector) is positive 
On the other hand we have the following:
(6)
Where 
the distance between the astronaut and the spacheship and 
the time. So, we have to find :
(7)
Finally:
The correct answer is anthracite
