Explanation :
Given that,
Mass of the spaceship 1, m = 300 kg
Initial momentum of the spaceship 1, p = 600 kgm/s
Momentum is the product of the mass and the velocity with which it is moving i.e.
p = m v
[tex]v=\dfrac{p}{m}[/tex]
[tex]v=\dfrac{600\ kgm/s}{300\ kg}[/tex]
[tex]v=2\ m/s[/tex]
The initial velocity of the spaceship 1 is 2 m/s.
Hence, this is the required solution.
