I PROMISE TO RATE AFTER IVE SEEN YOUR ANSWER

A 1500 kg car stopped at a traffic light is struck from the rear by a 700-kg car,
and they become entangled, moving along the same path as that of the originally
moving car. If the smaller car were moving at 15.0 m/s before the collision. (a)
What is the magnitude of the total momentum of the system before the
collision?
18000 kg.m/s
10500 kg.m/s
22500 kg.m/s
2200 kg.m/s
