Problem

A pendulum of length

1.0\,\text{m}

is hung from the ceiling of an elevator. The period of oscillation is observed to be

1.8\,\text{s}

. Calculate the magnitude and direction of the elevator’s acceleration (take

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

). (a)

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

downward (b)

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

upward (c)

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

upward (d)

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

downward
