Consider a 5.0 kg object traveling to the right at 25. m/s and colliding with a stationary 1.0 kg object. If the first object continues at 20. m/s to the right after the collision, what is its new momentum?

The conservation of momentum, means that before and after the collision, the momentum totals are the same...

original momentum 5 kg * 25 m/s = 125 kg -m/s

After collision 5 *20 = 100 kg-m/s

this means that the 1 kg object has the remainder of the momentum and is traveling at 25 m/s
