Problem

A student wants a pendulum clock that "ticks" every

1.50\,\text{s}

(one tick per swing, small amplitude). What pendulum length should the student build if the clock will operate where

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

? (a)

0.28\,\text{m}

(b)

2.2\,\text{m}

(c)

0.56\,\text{m}

(d)

1.1\,\text{m}
