What is the net momentum of the system BEFORE the collision?

• 10 x 9 = 90 kg*m/s

• 10 - 9 = 1 kg*m/s

• 10 + 9 = 19 kg*m/s

• 10 / 9 = 1.1 kg*m/s

What is the net momentum of the system AFTER the collision?

• 4 x 15 = 60 kg*m/s

• 4 + 15 = 19 kg*m/s

• 4 - 15 = -11 kg*m/s

• 15 / 4 = 3.75 kg*m/s
