Question

at what position, pendulum acquires the maximum kinetic energy?

Answer 1

when the pendulum reaches the very bottom of the swing, i.e the equilibrium/mean position it is at lowest point and greatest speed .this means that the pendulum has zero potential energy(with respect to its rest position) and maximum kinetic energy.

Answer 2
