Is the linear momentum conserved for all trials?

Answer 1

As we can see in the given table that experimental values pf velocities are different from theoratical values.

Since velocities are different from theoratical values so it means linear momentum is not conserved. We can see it in data table too. Actually it is may be because of direction change during the collision.
