This is our rocket design that we sketched out on paper. The design includes two 1 liter soda bottles and 4 fins made of cardboard. We are using 4 fins on the bottom to stabilize the rocket so it will launch straight up in the air. For the top of the bottle, we added a cone to make the rocket more aerodynamic and reinforced it to make sure the top of the rocket was secure and stable.
To find the height that the rocket reached, we used trigonometric equations, physics equations, and parabolas plotted on a graph.
These are our calculations for our initial velocity and trigonometric height. We found the the trigonometric height by multiplying 90 by tan(50) and then adding the time the rocket was in the air for, which was 3.25 seconds.
The equation of this parabola is y = -16x^2 + 52x, and this shows the rising of the rocket, its peak height, and the falling of it.
