Question 1026263
The formula T = 2π√(l/g) relates a pendulum's period, T, in seconds 
(the time it takes to swing back and forth) to its length, l, 
in centimeters using g, the gravitational acceleration of 981 cm/sec^2. 
How long would the pendulum have to be (to the nearest tenth of a centimeter) to make a pendulum with the given period? 
-------
sqrt(L/g) = T/(2pi)
------
L/981 = [T/(2pi)]^2
-----
Length = 981[T/(2pi)]^2
