You are told 3 things...1. That there are two objects with equal masses. 2. Both objects are in motion. 3. One object has a greater kinetic energy than the other. How is this possible? (1 point)

One object has a greater speed than the other object.
One object has a greater speed than the other object.
One object is blue and one object is red.
One object is blue and one object is red.
One object has a greater volume than the other object.
One object has a greater volume than the other object.
One object has a greater density then the other object.
One object has a greater speed than the other object.
The correct response would be:
One object has a greater speed than the other object.
To determine how it is possible for two objects with equal masses to have different kinetic energies, you need to understand the relationship between kinetic energy and speed. The formula for kinetic energy is KE = 1/2 * m * v^2, where KE is the kinetic energy, m is the mass, and v is the velocity (or speed) of the object.
Based on the information given, both objects have equal masses, so the mass (m) is the same for both objects. This means that the only way for one of the objects to have a greater kinetic energy is if it has a greater speed (v). So the correct answer is:
One object has a greater speed than the other object.
By knowing the formula for kinetic energy and understanding the relationship between mass and speed, we can reason that if two objects have equal masses but different kinetic energies, the one with the higher kinetic energy must have a higher speed.
