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 is blue and one object is red.
One object is blue and one object is red.
One object has a greater speed than the other object.
One object has a greater speed than the other object.
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.
None of these options are correct. The statement "both objects have equal masses" implies that the two objects have the same amount of matter, so their volume and density should also be equal. The only explanation for one object having a greater kinetic energy than the other is that the object with greater kinetic energy has a greater velocity.

I apologize if my previous response was not clear. Based on the information given, the only possible explanation is that one object has a greater speed than the other object. This would result in a difference in their kinetic energies, despite having equal masses.
A large truck and a small car are moving at the same speed, traveling up and down hills, and over bumpy roads. Which one has more kinetic energy?(1 point)
Responses
The car has more kinetic energy because it moves fast down hills.
The car has more kinetic energy because it moves fast down hills.
The truck has less kinetic energy because it has greater mass.
The truck has less kinetic energy because it has greater mass.
The truck has more kinetic energy because it has a greater mass.
The truck has more kinetic energy because it has a greater mass.
The car and truck have the same kinetic energy.
The truck has more kinetic energy because it has a greater mass.
One object has a greater speed than the other object.
The correct answer is:
One object has a greater speed than the other object.
To explain how this is possible, we need to understand the formula for kinetic energy. Kinetic energy (KE) is given by the equation KE = 0.5 * m * v^2, where m is the mass of the object and v is its velocity.
Since we are told that both objects have equal masses, the only way for one object to have a greater kinetic energy than the other is if it has a greater velocity (speed). This means that one object is moving faster than the other, resulting in it having a higher kinetic energy.
Therefore, the statement that one object has a greater kinetic energy than the other can only be explained by one object having a greater speed than the other object.
