# Question about momentum...?

Momentum, or P, = mv. And it is a law that momentum always has to he conserved through collisions. Suppose theirs an asteroid with a mass of 10^6 kg travelling at a constant velocity of 1 m/s. It hits another object with a mass of 1 kg. The momentum would be 10^6 kilogram meters/sec. so for the 1 kg object to...

It hits another object with a mass of 1 kg. The momentum would be 10^6 kilogram meters/sec. so for the 1 kg object to conserve that momentum, it would need to travel at a velocity of 10^6 meters per sec? Or 1000 km/sec? I cant see how that would be right.
