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.

Answer:

18.0625 feet

Step-by-step explanation:

Given : The pear had a speed of 34 feet per second.

To Find: Approximately how far up in the tree was the pear before it fell?

Solution:

We are given that assume that the acceleration due to gravity is 32 feet per second squared

Formula = s=\sqrt{2gh}

Where s is the speed , g is the acceleration due to gravity and h is the height

So, 34=\sqrt{2(32)h}

34^2=64h

1156=64h

\frac{1156}{64}=h

18.0625=h

Hence the pear was at height of 18.0625 feet before it fell.
