Question

A 2,000-kg car is sitting at rest in a parking lot. a bike and rider with a total mass of 60 kg are traveling along a road at 10 km/h. which system has more inertia? why?

A. the car has more inertia, as its mass is greater than the mass of the bike.
B. the bike has more inertia, as its mass is greater than the mass of the car.
C. the car has more inertia, as its mass is less than the mass of the bike.
D. the bike has more inertia, as its mass is less than the mass of the car.

Answer 1

The car has more inertia, as its mass is greater than the mass of the bike.

Step-by-step explanation:

The correct answer is A. The car has more inertia, as its mass is greater than the mass of the bike.

Inertia is the property of an object to resist changes in its motion. It is directly proportional to the mass of the object. In this case, the car has a mass of 2,000 kg, while the bike and rider have a total mass of 60 kg. Therefore, the car has more inertia.

For example, if a force is applied to both the car and the bike, it would be harder to change the motion of the car compared to the bike due to its greater inertia.
