Answer:

400 kg-m/s

Step-by-step explanation:

Given that,

Mass of the woman, m = 50 kg

Initial velocity, u = 8 m/s

Final velocity, v = 0 m/s

We need to find the change in momentum of the woman. It can be given by :


\Delta p=m(v-u)\\\\=50* (8-0)\\\\=400\ kg-m/s

So, the change in momentum is 400 kg-m/s.
