Question

Two billiard balls roll towards each other. They each have a mass of 0.3 kg. ball 1 is moving at 1 m/s to the right while ball 2 is moving at 1 m/s to the left. Calculate the momentum of the system.

with explanation pls ​

Answer 1

mass= 0.05kg

v=6m/s

pi=mvi=0.05*6=0.3kgm/s

p1f=0.3kgm/s

p2f=0.3kgm/s

p1f-p1i=0.3-0.3=0.6kgm/s

p2f-p2i=0.3(0.3) =0.6kgm/s

it was in opposite directions
