    Accelerating Work
AI Thread Summary
Determining when an object stopped accelerating is not feasible with just average speed, weight, and distance traveled due to insufficient data. The discussion suggests that applying physics retrospectively, especially in legal contexts like traffic incidents, is unreliable. Skid marks and vehicle damage often lack the necessary evidence for accurate analysis. If additional information, such as the rate of acceleration, is provided, it may allow for a more precise determination. Overall, more specific data is crucial for answering the question effectively.

If giving the average speed weight and distance traveled is it possible to work out when the object stopped accelerating

No. There’s insufficient data. This reads like an attempt to analyse a traffic incident. There’s virtually no chance that you can apply Physics post hoc here. Skid marks and vehicle damage are seldom good enough evidence in court.
 
No not traffic related but thanks for your input

Fair enough. I assume you must know more about the situation than you are telling us, right? Perhaps with the help of some of that information, the question can be answered...
 
If you are imagining an object that has accelerated up to a certain speed, then traveled at that (constant) speed to a certain location, then no, the information given would not be enough. However, if you also knew he rate of acceleration, then it should be possible.
 
I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
