* Car B has more inertia than Car A.

Here's why:

* Inertia is the tendency of an object to resist changes in its motion. The more massive an object is, the more inertia it has.

* Since Car B has a greater mass (2000 kg) than Car A (1500 kg), it will be harder to get Car B moving, and it will be harder to stop it once it's in motion.

In simpler terms: Imagine pushing a small car and then pushing a large truck. The truck will be much harder to move because it has more inertia.
