An object that has a small mass and an object that has a large mass have the same momentum. Which object has the largest kinetic energy?

Which object has the largest kinetic energy?
Answer to Problem 1CQ
Largest kinetic energy will be of the smaller object.
Explanation of Solution
Given info:
An object that has a small mass and an object that has a large mass have the same momentum.
As we know the momentum is the same therefore the speed for the smaller mass object will be more. Since the kinetic energy of an object is momentum times of speed. Therefore, for the same momentum, the mass of higher speed will have more energy i.e. the smaller mass.
Therefore, the largest kinetic energy will be of the smaller object.
Conclusion
Largest kinetic energy will be of the smaller object.
