A cart-force model
Original fictional classroom scenario; all measurements and models are hypothetical.
In a hypothetical frictionless horizontal model, a 3 kg cart experiences a net force of 12 N east. It starts at rest. For a separate collision, a 2 kg cart moving east at 3 m/s sticks to a stationary 1 kg cart; external horizontal impulse during that collision is negligible.
