SUMMARY
In momentum calculations, the mass of colliding objects often cancels out when determining the y-components of momentum due to their opposite directional velocities. This principle is grounded in the conservation of momentum, which states that the total momentum before and after a collision remains constant. The cancellation occurs because the momentum vectors of the objects, when summed, result in a net effect that is independent of their masses, provided they are equal and opposite.
