Which series of steps describes how to demonstrate conservation of momentum in a system of two moving particles that collide? (1 point)

Determine the momentums of the two particles before the collision and add them together. Determine the momentums of the two
particles after the collision and add them together. Verify that both sums are the same.
Determine the momentums of one of the particles before and after the collision and add them together. Determine the momentums
of the other particle before and after the collision and add them together. Verify that both sums are the same.
Determine the momentums of the two particles before the collision and add them together. Determine the momentums of the two
particles after the collision and add them together. Verify that both sums are zero.
