Followup Response to my critics:
Please forgive my transgressions of not giving perfectly accurate numbers...
Critic #1 Showcase Feat. Hovsky
You're pulling the impact duration out of thin air, and suggesting that the truck is brought to a halt by the impact. Both of those are ridiculous and have a HUGE impact on the result. So nice calculation, but it's essentially meaningless.
Using state of the art collision software also known as VLC, I found out the collision time by analyzing how many frames there were in in the collision. A standard YouTube video has a frame rate of 30 frames per second. The collision was 3 frames long. Proof The remaining time was just the impetus of the truck just dragging/pushing the carjackers forward. Here is a professionally-made force time graph detailing the collision. Visual
Calculations:
Therefore the collision time was to be justified to be 0.1 seconds.
2.Final velosity rxpk and Hovsky argued that the final velocity was not 0. Yes I agree with you on that. But it can basically be assumed as zero since it does not have a great impact (pun not intended) on the final force. But I'll humor you and I assume that the final velocity was around 3 mph or 1.34 m/s
Calculations: 1. F = [m(vf-vo)]/t 2. F = [2041.17(1.34-6.7056)]/0.1 3. Force = -10940.7 N
This is only around 20000N in difference from my original calculations which is only a drop in a bucket. Ok... now that is only around 3.5 times the bite force of a large 6.7m adult saltwater crocodile. Still hurts!!!!
Critic #2 Showcase Feat. forward_x
but did you account for the drivers body weight
First of all you should be addressing mass instead of weight. There is a huge difference. Answer to your question assuming you meant mass: Yes and no. The driver's mass is negligible compared to the total mass of the truck. I assume there wasn't 4 sumo wrestlers in the back.
TL;DR getting hit by a truck still hurts a lot
