Assignment:
The period T (time in seconds for one complete cycle) of a simple pendulum is related to the length L (in feet) of the pendulum by the formula 8T^2=(3.14)^2L. If a child is on a swing with a 10 foot chain, then how long does it take to complete one cycle of the swing?
Provide complete and step by step solution for the question and show calculations and use formulas.
