Calculate approximate speed of a collision?

AI Thread Summary
Estimating the speed of a collision with limited information is challenging, as physics alone cannot provide a precise answer. In this scenario, one vehicle is stationary on dry pavement and struck from behind by another vehicle, resulting in a 30-meter push. The weight of both vehicles is approximately 1,800 kilos each, and there is no evidence of braking. While a more detailed analysis is not feasible, legal recourse may be available depending on the circumstances. Ultimately, insurance companies will handle the claims process.

Hi - I know that the information that I can provide here is too limited for a totally accurate answer, but is it possible to come up with a reasonable estimate? One vehicle, snow tires, on dry pavement, 6 degrees celsius, is motionless. Second vehicle strikes first in the rear. No evidence of any braking. First vehicle is pushed 30 meters. Weight of both vehicles and cargo is approximately 1,800 kilos each. Thank you for any replies.

Hi and welcome.
PF gets regular posts concerning traffic accidents. Unfortunately there is no way to work out problems like you have presented, using just Physics. Apart from saying that there must have been more than just a 'nudge' involved in this collision, neither I nor any of PF can commit to a more detailed comment. Depending on your circumstances, you might get some satisfaction in a court case if you have a good lawyer but, unless it is a criminal case. It just has to be down to the Insurance Company, I'm afraid. Sorry.
 
Well said, thank you @sophiecentaur.

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
