The period T (time in seconds for one complete cycle) of a simple pendulum is related to the L (in feet) of teh pendulum by the formula 8T^2=pie^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.\r
\n" ); document.write( "\n" ); document.write( "Your formula is confusing.
\n" ); document.write( "It could mean (pi)(e^2)L or (pi)^(2L) or (pi^2)L
\n" ); document.write( " Assuming it means the following you should get:
\n" ); document.write( " 8T^2=(pi^2)L
\n" ); document.write( " 8T^2=(3.1416...^2)(10)
\n" ); document.write( " T^2 = (1/8)(9.86...)(10)
\n" ); document.write( "T^2=(1/8)(98.6...)
\n" ); document.write( "T^2= 12.337...
\n" ); document.write( "T= 3.51 seconds\r
