Suppose the initial kinetic energy and final potential energy in an experiment are both zero. What can you conclude? A. The final kinetic energy is zero. B. The initial potential energy is zero. C. The final kinetic energy is equal to the initial potential energy. D. The sum of the initial and final kinetic energies is zero.

C. The final kinetic energy is equal to the initial potential energy.

Explanation:

Based on the Principle of energy conservation:

Sum of the Initial Energy = Sum of the Final Energy

Initial Kinetic Energy + Initial Potential Energy = Final Kinetic Energy + Final Potential Energy(1)

Since according to the question:

Initial Kinetic Energy = 0

Final Potential Energy = 0

The equation (1) above reduces to

Initial Potential Energy = Final Kinetic Energy

the first, second, and fifth options

increase masses, decrease separation
