Inertia is directly related to the mass of an object; the greater the mass, the greater the inertia. Therefore, the object that represents the greatest amount of inertia among the options provided is:
**pushing a parked 3,000-kg truck**
This is because the truck has the highest mass compared to the other examples, which means it has the greatest inertia that needs to be overcome to change its motion.
**pushing a parked 3,000-kg truck**
This is because the truck has the highest mass compared to the other examples, which means it has the greatest inertia that needs to be overcome to change its motion.
