Answer: 6 metres per second. Answer: Since momentum = velocity x mass, just divide the momentum by the mass. The mass for spaceship #2 is irrelevant for this problem.

Since you haven't provided me with any units for the speed I will assume it as m/s
As we know
Mass of spaceships=150 kg
Velocity of spaceship 1= 0 m/s
Velocity of spaceship 2= 6 m/s
Before collision
P=Momentum of spaceship 1 = m×v =150×0=0
Q=Momentum of spaceship 2=m×v =150×6=900
After collision both the spaceships stick together as one , so the mass of body becomes 300 kg.
Using the principle of conservation of linear momentum
Momentum before collision=Momentum after collision
P+Q = 300×V
900=300×V
Hence V=3 m/s.
The speed of spaceships stuck together after collision is equal to 3 m/s.
