Answer:
, where m is the mass of the pendulum
Explanation:
As we know that mechanical energy is the sum of kinetic energy and potential energy.
Since the Pendulum at its highest point has zero velocity, its kinetic energy at this point is equal to zero.
Thus, here in this mechanical energy will be equal to the potential energy only.
Potential energy is equal to the product of gravity constant, mass of the body and the height of the pendulum
Thus,



Hence,
