Consider a simple pendulum of length L that has a small mass (the bob) of mass m attached to the end of its string. If the pendulum starts out horizontally and is released from rest, show that
(a) The speed at the bottom of the swing is vmax = √2gL and
(b) The tension in the string at that point is three times the weight of the bob, or Tmax = 3mg.
