Answer:
The momentum of the two balls if they stick together after the collision is 0.6 kgm/s.
Explanation:
Apply the principle of conservation of linear momentum, the total momentum before collision is equal to the total momentum after collision.
Given;
initial momentum of the cue ball = 0.5 kgm/s
initial momentum of the 8 ball = 0.1 kgm/s
[tex]P_{before} = P_{after}\\\\0.5 \ kgm/s + 0.1 \ kgm/s = P_{after}\\\\P_{after} = 0.6 \ kgm/s[/tex]
Therefore, the momentum of the two balls if they stick together after the collision is 0.6 kgm/s.
