A group of friends is playing billiards. Ronald, one member of the group, hits the cue ball on the way to another ball. The cue ball has a 0.1-kg mass, and the other ball it hit has a
velocity of 2 m/s. If the collision is completely elastic and the cue ball rolls with a
velocity of 0.8m/s after the collision, what is the mass and velocity of the other ball?​

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
