volume_mute

In part 3, of the figure, arrow XA, which represents the sideways momentum of A after collision, must be the same length as arrow XB, representing ball B's sideways momentum.  Vector YA and YB represent the downward momenta of balls A and B.

The total of these two vectors must equal what momentum?

The momentum of A after collision
The momentum of B before collision
The momentum of A before collision

Correct Answer

The momentum of A before collision
