3. One object has a greater speed than the other object.
The kinetic energy of an object is given by the equation KE = 1/2 mv^2, where m is the mass of the object and v is its velocity. Since the masses of the objects are equal, the only way for one object to have a greater kinetic energy than the other is if it has a greater velocity or speed. The object with a higher speed will have a higher kinetic energy.
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. One object has a greater density then the other object
2. One object has a greater volume than the other object
3. One object has a greater speed than the other object
4. One object is blue and one object is red
