Answer:
Work individually or in teams of two to construct and launch paper rockets using a teacher-built PVC-pipe launcher.
Following the flight of their rocket, calculate the altitude their rocket achieved.
Based on the flight performance of their rockets, analyze their rocket designs, modify or rebuild them, launch again, and calculate the altitude achieved to determine if their changes affected the performance of the rocket.
Conclude the activity by writing a post-flight mission report.

Answer:
Step-by-step explanation:
Known facts:
- the ball dropped from a height of 64 feet
- function
First question:
- the ball hits the ground when h(t) = 0, thus we get the equation
So the ball hits the ground in 2s
Second question
- to find how long it takes the ball to fall 36 feet, we must set h(t) = 64 - 36 = 28
So the ball hits the ground in 1.5s
Hope that helps!
