Keeping Momentum

DoNow: A 100 kg mass moves with a velocity of 2 m/s in a collision course toward a 200 kg mass moving with a velocity of 3 m/s toward the 100 kg mass.
(a) Illustrate the situation.
(b) Calculate the initial momentum of each mass before the collision.
(c) Calculate the total momentum of the system of masses before or after the collision.
(d) In this situation, the collision is inelastic, what speed and direction does each object move?
(notes) (video)

AIM: I can describe when and how to apply the Conservation of Momentum Law to predict the motion of objects in a collision or explosion type scenarios.
