b. The kinetic energy does not depend on the chosen reference.

What is kinetic energy?

Kinetic energy is a form of energy that an object possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its current velocity. Kinetic energy is a scalar quantity, meaning it only has magnitude and no direction. The formula for calculating kinetic energy is:

KE = 1/2 × m × v²

Where KE is the kinetic energy, m is the mass of the object, and v is its velocity.

The concept of kinetic energy was first introduced by the French mathematician Gaspard-Gustave de Coriolis in 1829. It was later developed by other scientists such as James Prescott Joule and Hermann von Helmholtz.

Read the fable. Then, answer the question that follows."The Mouse and the Weasel" from Aesop's Fables A little hungry Mouse found his way one day into a basket of corn. He had to squeeze himself a good deal to get through the narrow opening between the strips of the basket. But the corn was tempting and the Mouse was determined to get it. When at last he had succeeded, he gorged himself to bursting. Indeed he became about three times as big around the middle as he was when he went in. At last he felt satisfied and dragged himself to the opening to get out again. But the best he could do was to get his head out. So there he sat groaning and moaning, both from the discomfort inside him and his anxiety to escape from the basket. Just then a Weasel came by. He understood the situation quickly. "My friend," he said, "I know what you've been doing. You've been stuffing. That's what you get. You will have to stay there till you feel just like you did when you went in.
