Answer:
2000 kg m/s
Explanation:
The momentum of an object is a vector quantity whose magnitude is given by
[tex]p=mv[/tex]
where
m is the mass of the object
v is the velocity of the object
and its direction is the same as the velocity.
In this problem, we have:
- Spaceship 1 has
m = 200 kg (mass)
v = 0 m/s (zero velocity)
So its momentum is
[tex]p_1 =(200)(0)=0[/tex]
- Spaceship 2 has
m = 200 kg (mass)
v = 10 m/s (velocity)
So its momentum is
[tex]p_2=(200)(10)=2000 kg m/s[/tex]
Therefore, the combined momentum of the two spaceships is
[tex]p=p_1+p_2=0+2000=2000 kg m/s[/tex]
