Question 195454: 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 8T2 = 2L. If a child is on a swing with at 10-foot chain, then how long does it take to complete one cycle of the swing?
8T2 = 2L =
8T2 = 3.142(10)=
8T2 = 9.86(10)= 98.60
8T2 = 398.60

8T%5E2+=++2L
Given L = 10
8T%5E2+=+2%2A10
T%5E2+=+20%2F8
T+=+sqrt%285%2F2%29
T+=+1.58 seconds
