SOLUTION: 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=pi^2L. If a child is on a swing

Question 126320: 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=pi^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.

Just plug in the given value for length and do the arithmetic.

.

Rationalize the denominator:

.

Now you can use the calculator to find the approximate decimal value, or leave it alone for the exact answer
