The potential energy is converted into kinetic energy.
 Therefore, for conservation of energy we have:
 mgh = (1/2) m * v ^ 2
 From here we clear the speed:
 v = root (2 * g * h)
 The height will then be:
 h = v ^ 2 / (2 * g)
 Substituting the values:
 h = (34) ^ 2 / (2 * (32))
 h = 18.0625 feet
 Answer: The pear before it fell was 18.0625 feet up in the tree.
