80m/s
40 m/s
momentum = mass x velocity, so velocity is momentum/mass. If the question asks for the magnitude then it's probably the absolute magnitude rather than a directional value (which would be negative as the space ship is heading to the left.
75m/s
An object that decreases its speed also decreases the magnitude of its velocity and decreases the magnitude of its momentum. Momentum is mass time velocity. Less velocity, less momentum. Technically, velocity is a vector and therefor momentum is a vector. One can speak of smaller or larger magnitudes of a vector, but not smaller and larger vectors because vectors have magnitude and direction. Speed is the magnitude of velocity.

Multiply mass x velocity for each spaceship. Add the results.
Momentum = (mass) times (velocity)9,000 = 300 x speedSpeed = 9,000 / 300 = 30 meters per second

momentum = mass × velocity Assuming they are separate, the total momentum is 200 kg × 0 m/s + 200 kg × 10 m/s = 2000 kg m/s
momentum must be conserved momentum = mass*velocity initially momentum = 150*6 +150*0 = 900 kgms-1 final momentum = 300*combinedvelocity = 900 so the final velocity must be 3 ms-1
Use the symbols 'm' for the object's mass, and 'v' for its velocity. Momentum is defined as 'mv' = the product of the object's mass and velocity. If the velocity doubles, then the new momentum is 'm' times '2v' = 2mv = 2 times (mv). This is just double the original momentum. So you can see that the magnitude of momentum is directly proportional to the magnitude of velocity, provided the mass remains constant.
