### In an isolated system two cars each with a mass of 1500 kg collide Car 2 is initially at rest while Car 1 was moving at 20 m s What is their final speed?

Assuming the impact was elastic, Car1 will not be at rest, and Car2 will move at 20m/s at the same direction Car1 was previously moving.

### In an isolated system two cars each with a mass of 1500 kg collide. Car 1 is initially at rest while Car 2 was moving at 5 ms. What is their combined momentum after the collision?

Law of Conservation of Momentum: The total momentum after the collision is equal to the total momentum before the collission.
