Intro:
During this project in Pre-cal, we build and launched a bottle rocket in order to understand projectile motion. Projectile motion is the motion of an object thrown or projected into the air, subject to only the acceleration of gravity. The object is called a projectile, and its path is called its trajectory.

The first step was finding out what we needed to make the rocket launch successfully. We got a lot of our inspiration from the rocket that launched successfully in the prior Pre-cal class. We put a lot of thought into the wings because when it catches the wind while it shooting up it causes the water bottle to spiral which makes it go further up.
The Launch:
The Launch:
After the construction of everyone's rockets was complete, we launched them with a water bottle rocket launcher on the track/Soccer field.

Trigonometric Calculations:
Final Position = (initial velocity) x (time) – (0.5)(32)(time)^2
● Final Position = 0 (the rocket is back on the ground)
● Time = the total time the rocket was in the air Our Time: 5 seconds
● Calculate initial velocity by manipulating the equation until you isolate for velocity
