Solution
- The initial height based on the question is 12 ft and the initial velocity is 81ft/s
- Thus, the equation governing the movement of the object is:

- We can plot the graph of the equation of the object's movement to see its path as shown below:
- The x-axis gives the time, while the y-axis gives the distance covered.
Question A:
The object will reach maximum height at 2.53 seconds
Question B:
The object's maximum height is 114.52 ft
