1. A pendulum with a length of 30 cm swings back and forth as
shown in the figure above, at each turn around point it stops and
it starts accelerating until reaching maxium velocity at the botton
(equilibrium position), at which point it starts slowing down. If
the maximum angle is 11 degrees, what is its maximum
velocity in m/s? (Use g = 10.0 m/s2 and assume
there is no friction).
