Answer :
The total momentum of the system after collision is 12 kg-m/s.
What is collision?
- Two items collide when they come into brief physical touch with one another. Or to put it another way, a collision is a reciprocative engagement between two masses that lasts for a relatively brief time and results in a change in momentum and energy.
- There are, however, three distinct types of collisions: elastic, inelastic, and absolutely inelastic. I'll say it again: in all three categories of collisions, momentum is preserved.
- The transformation of kinetic energy characterizes collisions.
- A collision is an instantaneous interaction between two or more bodies, occurring at the same time, that modifies the motion of the bodies involved as a result of the internal forces acting on them.
- Conflicts involve troops (there is a change in velocity). Before impact, there is a significant differential in velocity that is this size.
