Answer :
A 12 kilogram cart is moving at a speed of 0.25 meter per second after the speed of the cart is tripled the inertia of that cart will be will be 12 kilograms.
The inertia of an object is a measure of its resistance to changes in its state of motion. Inertia is directly proportional to the mass of the object. This means that if the mass of an object is increased, its inertia will also increase. In this case, the mass of the cart is 12 kilograms, and its speed is 0.25 meters per second. If the speed of the cart is tripled, the inertia of the cart will not change because the mass of the cart remains the same. The inertia of the cart will still be 12 kilograms. It is important to note that the speed of an object does not affect its inertia. Inertia is determined solely by the mass of the object. Every item maintains its condition of uniform motion in a straight direction or of rest unless it is compelled to do otherwise by forces applied to it. The Latin word iners, which means idle or sluggish, is where the word "inertia" originates. The resistance of any physical object to a change in velocity can also be referred to as inertia.
