Answer:
50kgm/s
Step-by-step explanation:
From the law of conservation of momentum, a system that starts with an initial momentum of 50kgm/s will end up with a momentum of 50kgm/s in its final state.
- The law of conservation of momentum states that "in an isolated system, momentum is neither created nor destroyed but transformed from one form to another".
- From this law, the starting and ending momentum must be the same.
