Answer 2

Tennis ball has least inertia.

• Inertia is the property of mass of a body. It is the property by which a body remains at rest if it is initially at rest or remains in motion if it is in motion until and unless an external force is applied to it.
• The object with lowest mass will have least inertia. Since the tennis ball is the lightest out of all the given options hence it will have the least inertia.
• The object that has greatest mass will have highest inertia, in this case car will have the highest inertia.
