Hi everyone so I am stuck at home doing school work because of the coronavirus but have been able to get some work done like my first home make parachute is complete and I just need to set up my drop zone an Ipad for testing. Me and my team Bomb.com are delivering ingredients to people at home so when this type of situation has happened and is somewhat dangerous to go outside because of the virus you can get a great home-cooked meal without having to leave your house. our criteria are:
- The velocity of the drop (m/s): Lands with a speed of 1m/s to 2m/s
- Accuracy of the drop: It must land 50cm within the target.
- Condition of the product: The product inside the package must be not harmed.
My research question is how the shape and size of the spill hole will affect the accuracy and softness of the landing. I am going to make a change to everything. (box, string and parachute) I am going to make everything smaller by half like the diameter on the canopy is now 37.5 cm. I am making a change to the variable drop hight it is now 3.7m or 370 cm. Also what I will be using in my data table it used to be the max speed and now it is the speed right before the box hits the ground but everything else will stay the same.
Procedure
1) Clear the landing area of people.
2) Person A: Set up the iPad on the shelf in a position that the camera would capture the 1m box and at least a height of 4 meters.
3) Person B: Move the hook machine to the pole closest to you. Connect the package to the hook machine over the balcony. Then push it back 37cm.
4) Person B: Flip the switch on of the box (main power source) attached on the machine. After that, turn on the remote.
5) Person B: Vocally warn your teammates with a five-second countdown. Person A: Press record on the iPad as soon as Person B starts counting to ensure a full scene of the package falling.
6) Person B: Press the O button (the release button) on the bottom of the remote.
7) Person B: After your package has been dropped, press on the B button once more to re-position the hook.
8) Person A: After the box has landed and stopped moving, stop the video and trim out the ineffective bits.
9) Repeat steps 1 to 9 at least three times.
10) Turn off the remote and the box (main power source) attached to the machine.
11) Send everybody the videos.
12) Everyone will go onto Logger pro and record the Y-Axis Final Velocity (Right before it impacts the ground) and the accuracy of the drop (how far away from the target point).
13) We would then analyze the Data (Number of Bounces, Accuracy, etc.).
14) Insert our findings into the data table.

I am going to use the mean method to get the average of my trials.
