Gravitational potential energy is given by:

$\overline{){\mathbf{U}}{\mathbf{=}}{\mathbf{m}}{\mathbf{g}}{\mathbf{h}}}$

From the conservation of energy, the maximum kinetic energy is equal to the potential energy of the system.

Rank each pendulum on the basis of the maximum kinetic energy it attains after release. Rank from largest to smallest. To rank items as equivalent, overlap them.
