Problem

A simple pendulum of length

0.80\,\text{m}

is momentarily displaced along its arc by

2.0\,\text{cm}

and released. Find the magnitude of its instantaneous tangential acceleration at that position. (Take

g = 9.8\,\text{m}\,\text{s}^{-2}

.) a)

0.50\,\text{m}\,\text{s}^{-2}

4.9\,\text{m}\,\text{s}^{-2}

0.25\,\text{m}\,\text{s}^{-2}

1.2\,\text{m}\,\text{s}^{-2}
