Apendulum has 359 j of potential energy at the highest point of its swing. how much kinetic energy will it have at the bottom of its swing?

Explanation:

According to law of conservation of energy, energy can neither be created nor it can be destroyed. It can only be transformed from one form to another.

Therefore, when pendulum is at highest point of its swing then it had only potential energy and zero kinetic energy. But when swing reaches at the bottom then potential energy converts into kinetic energy as height is zero.

Hence,        potential energy = kinetic energy.

Thus, we can conclude that kinetic energy at the bottom of swing of pendulum is 359 J.

the correct answer would be d. hope this !
