“Oh hey!”
“Your back.”
“Now continue reading.”
Introduction
“Promising that the products are safely dropped and will land accurately at your front door 10cm within the mark.” -Bomb.com
“How does the length, material of the suspension ropes affect the accuracy of the drop and the speed of the drop?” My group, Charlott and myself, is researching this. Basically, meaning that this is our research question.
Our Prediction
Predicting that the best design for our variable is using nylon made 35cm suspension ropes, because based on Prezi.com, it showed how the longer the ropes are, the longer the hang time was. Which caused more air resistance. Gravity was pulling on the object all the time, while with the shorter ropes, the gravity was actually applying more force to the object.

Our Design Sketch
“Hey!”
“Read the procedures first before dropping!”
Data Collection Procedure
Person A: Charlott Person B: Sophie
1) Clear the landing area of people
2) Set up the iPad – Person A
3) Connect the package to the hook machine over the balcony, vocally warn your teammates with a three second countdown
4) Press record to collect data on the Y velocity of the package along with where it will be landing.
5) After the box has landed and stopped moving, stop the video and trim out the bits you don’t need.
6) send to everybody the video/s.
7) Everyone in their group goes on to Logger Pro to analyze the videos but the results in the data table
8) analyze the videos but the results in the data table
