**drwls**, Sunday, July 11, 2010 at 11:05amLet A be the pendulum angle, which vaires sinusoidally with time. R is the pendulam length

R sin A = X

Xm = 2.0 sin 25 = 0.845 m is the oscillation amplitude (measured horizontally)

X = Xm sin (w t)

is the equation of motion

w is the angular frequency

w = sqrt(g/R) = 2.21 rad/s

Vmax = w*Xm = 2.21 rad/s*0.845 m

= 1.87 m/s
