A dog and a mouse run along a road with the same kinetic energy. The faster runner is the

Question

Quizplus · Accepted Answer

The faster runner would be the one with smaller mass since kinetic energy depends on both mass and velocity. Since the dog is much larger than the mouse, it would have a larger mass, and therefore a lower velocity, compared to the mouse. Therefore, the mouse would be the faster runner with the same kinetic energy as the dog.
