#### Solution Preview

Step 1.

At the highest point, the velocity is zero. Therefore, the total rise time is:

(1) t=(Vf - Vo) / (-g)

By substituting knowns ...

#### Solution Summary

The expert finds the change in height in the last 1.5 seconds. In a step by step solution, the calculations and explanations are clear.
