Problem

A pendulum of length

1.0\,\text{m}

is released from rest after being pulled aside so that the string makes an angle of

30^{\circ}

with the vertical. Neglecting air resistance, find the speed of the

0.20\,\text{kg}

bob as it passes through the lowest point. a)

3.2\,\text{m}\,\text{s}^{-1}

1.1\,\text{m}\,\text{s}^{-1}

1.6\,\text{m}\,\text{s}^{-1}

2.3\,\text{m}\,\text{s}^{-1}
