**drwls**, Wednesday, May 12, 2010 at 9:36amGet the length L from the period P.

The period is 2 seconds because it takes 1/2 second to accomplish 1/4 of it. (maximum deflection to zero deflection)

P = 2 pi sqrt(L/g)= 2 seconds

L/g = (1/pi)^2

L = 0.994 m

The maximum height tht it gets raised is

h = L (1 - cos 8) = 0.00967 m

The maximum K.E. is M g h (which is the maximum potential energy)

Use that to compute Vmax
