A correct electrical-mechanical analogy sees the electric energy in a capacitor

Question

A correct electrical-mechanical analogy sees the electric energy in a capacitor and the magnetic energy in an inductor that is connected to the capacitor by means of a wire as respectively analog to O O O O O the kinetic energy of a sliding puck and the work done by friction with the ground. the gravitational energy of a lifted box and the work done by the applied force on it. the elastic energy of a spring and the kinetic energy of a ball attached to the spring the positive energy of the Yang and the negative energy of the Yin the gravitational energy of a falling ball and the kinetic energy of that falling ball.

Explanation / Answer

a)
The answer is the elastic energy of a spring and the kinetic energy of a ball attached to the the spring.
For the capacitor inductor system, the energy stored in the inductor (1/2 LI2) and the energy stored in the capacitor (1/2 CV2) oscillates with a frequency similar to the potential energy (1/2 kx2) of the spring and the kinetic energy of the mass (1/2 mv2) attached to it.

b)
Answer is a current flowing through it that oscillates in step with the generator voltage.
For a resistor there is no phase shift between current and voltage unlike a capacitor or an inductor.
