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).
