you are told three things…1. That there are two subjects with equal masses. 2. Both subjects are in motion. 3. One object has a greater kinetic energy than the other. How is this possible?
1. One object has a greater speed in the other object.
2. One object is blue and one object is red.
3. One object has a greater volume in the other object.
4. One object has a greater density than the other object.
The correct answer is 1. One object has a greater speed than the other object.
Kinetic energy is given by the equation KE = (1/2)mv^2, where m represents mass and v represents velocity (speed). Since both subjects have equal masses, the only way for one object to have a greater kinetic energy than the other is if it has a greater speed. The other options given (2, 3, and 4) are unrelated to kinetic energy and do not explain how it is possible for one object to have greater kinetic energy than the other.
