1. ### Technologies or devices or knowledge for cars in specifics subjects

I do a small theoretical project, in this project I need to investigate some technologies or devices or knowledge that must to be related to cars or to futures cars or cars industry, it can be all the kinds of cars, not only private car, it can be also buses, tractors, trucks or all others kinds...
2. ### Newtonian force as a covariant or contravariant quantity

I recently came across a very cool book called Div, Grad, and Curl are Dead by Burke. This is apparently a bit of a cult classic among mathematicians, not to be confused with Div, Grad, Curl, and All That. Burke was killed in a car accident before he could put the book in final, publishable...

### 3 Car Collision

Hello I am new here. I am currently working on my masters in Engineering Tech and have looked to this Forum for help before. I am posting here b/c I am looking for some help... my husband was in a car accident and was the notorious middle car. The cars in his lane went from 35-40 to 0 pretty...
4. ### Choosing which types of Distribution

Given the following distributions I have to choose which one to use under the given scenario. Distributions - Binomial - Poisson - Pascal - Multinomial - Hypergeometric - Normal (z distribution) Scenarios: a. I love snickers so I pull candy from the bag and immediately putting...
5. ### Violation of simultaneity - real of frame-dependent perception?

I am trying to understand what 'violation of simultaneity' really means, and whether it has any real importance (i.e. why was it introduced?). The Wikipedia note on this (Topic: Relativity of Simultaneity): "... the relativity of simultaneity is the concept that simultaneity–whether two...
6. ### Seat belt forces on car

Hi all, I'm having an online discussion and curious to know about the forces a 3-point seat belt has on a car. One guy is fitting this retractable belt to his car. The retractor and anchor mount at one bolt hole, the anchor is off centre, it attaches via a steel extension piece, the section...
7. ### Is it better to accelerate into a head on collision?

Naturally, one would think, the faster your going the more energy you will create and the harder you will hit. But take a deeper look. Under the basis that in a car accident, it isn't the "Crash" that kills you, but the stop (inertia). If you were to be involved in a head on collision with an...
8. ### Automotive Help Needed to understand a Car Accident

Dear All, I was involved in a car accident. The facts of the case as follow: Location: At a side road joining into a major road. The side road slopes downwards on a 10 degree gradient to the major road. My car was the first vehicle awaiting to exit into the major road. Background of...
9. ### Help me out please - Car accident analysis

Help me out please -- Car accident analysis hey guys, I have a question... If car 1 weighing in at 4400lbs is traveling at 0 degree heading at 55 MPH and is impacted on the right side by car 2 weighing in at 2700 lbs from a 90 degree heading traveling at 5 mph and the departure angle of car 1...
10. ### Will Smart Car Protect you in a High-Speed Accident?

Good day, I'm curious about the Smart Car's commercial. It says it can withstand up to 3 tons of weight. Now, I want to know if it can protect the passengers in it if a vehicle weighing 1 ton running at 150 kph crash into it? May I know what's the formula to answer my question? Thanks in...
11. ### Car Accident Question

Recently I have been involved in a car accident, and would like to figure out what was the speed of the other car that crashed into us. I only have two figures, the distance from the point of impact to where the car stopped and the mass (of both cars); and also, the final velocity which is 0...
12. ### Three Car Accident, Domino Effect

My mom and I were involved in a 3 car accident. We were the middle car. The car in front of us had come to a complete stop in bumper to bumper traffic. We made a sudden stop but stopped completely. Seconds later the car from behind us hit us with great force sending us into the car in front...
13. ### Car accident

A car is at rest , the driver let's off the brake and hits car in front, the cars were 5 feet apart prior. No damage is apparent, later, front car claims back chrome bumper has dent. Is there a formula to prove or disprove the required force to dent the chrome bumper? What other info would be...
14. ### Suppose you are a police investigator and are investigating two car accidents. Before

Suppose you are a police investigator and are investigating two car accidents. Before you even go to either accident scene, you know (interestingly) that both accidents were identical head – on collisions with identical cars moving at identical speeds, but in one case the cars locked bumpers...
15. ### Velocity of Head from Car Accident

My friend was in a head-on collision this week. They were traveling approximately 35 mph. A car collided with them head-on traveling at approximately 30 mph. The airbag deployed, and the impact caused a tremendous contusion on my friend's forehead, but no skull fractures. It's been years since...
16. ### I am researching a car accident I was in: I need to know how far my car was pushed

Hello, I am not a big math guy, although I do have a bachelors degree I don't remember any of my formulas from high school lol. I was involved in a car accident and I am researching the physics of the accident. I want to try and approximate the speed of the vehicle that hit me broad...
17. ### Car Accident Reconstruction

My physics professor gave us a lab in which we have to do accident reconstruction. The difficulty I am having is that we have not gone over how to calculate collision with coefficients of restitution in class. So far we've only done completely elastic or inelastic, yet now he expects us to do...
18. ### Mysterious car accident

I was in a car accident involving an eighteen-wheel truck. The driver thinks the truck hit the car. I was in the passenger seat and I think the car hit the truck. Can someone give their opinion given the details: The car was traveling in the left lane at about 70 miles on the highway. The...
