Problem

GREPhysics.NET Official Solution

Alternate Solutions

Mechanics $\Rightarrow$ }Lagrangian

Recall Hamilton's Principle (of least action),

$\int_{t_1}^{t_2} L dt, <br />$

where $L=T-V$ is the Lagrangian and $T$ is the kinetic energy and $V$ the potential energy. The potential energy is given in the problem. The choice is obviously (A).

An extremum is a point where the minimum or maximum of a function occurs. Usually, in the realm of classical mechanics, it's a fancy way of referring to the Lagrangian.

I was thinking is this just this easy or is this a trick question. Turns out it is just this easy.
