Problem

A simple pendulum of length 1.0 m1.0\,\text{m} is driven by an external force of adjustable angular frequency. For which of the following driving angular frequencies will the pendulum swing with the greatest amplitude? (Take g=9.8 m s−2g=9.8\,\text{m\,s}^{-2}.) (a) 4.0 rad s−14.0\,\text{rad\,s}^{-1} (b) 3.0 rad s−13.0\,\text{rad\,s}^{-1} (c) 6.0 rad s−16.0\,\text{rad\,s}^{-1} (d) 2.0 rad s−12.0\,\text{rad\,s}^{-1}
