Question 1077759

The time period of a simple pendulum is directly related to the square root of its length. an 8 foot pendulum has a period of 3.2 seconds. find the period of a grandfather clock that has a pendulum of length 3 feet .  Need help with developing the formula to solve problem.
<pre>Formula: {{{matrix(1,3, T, "=", k * sqrt(L))}}}, where:
{{{T}}} = Time
{{{k}}} = Constant of Proportionality
{{{L}}} = Length
Calculate it and you should get a time of: {{{highlight_green(matrix(1,2, 1.959591794, seconds))}}}
