AI Thread Summary
To prove that the car wouldn't have left the ground while crossing railroad tracks, it's essential to calculate the minimum speed required for a vehicle to become airborne based on the angle of the tracks. The key formulas involve physics concepts such as projectile motion and the relationship between speed, angle, and gravitational forces. Experimentation is suggested, but concerns about law enforcement presence complicate this approach. Understanding the mass of the car and the specific angle of the tracks will be crucial for accurate calculations. Proper application of these principles can help build a case against the ticket received.

I got a ticket for "jumping railroad tracks," so I have to prove that at the speed I was going, my car wouldn't have got off the ground going over those railroad tracks. I think I'm going to have to find out how fast a car with the mass of my car would have to be going to get air over track of whatever angle the tracks I went over are, but I haven't been in physics class for 6 months, so I'm pretty lost. Someone please explain how I can do this. What formulas and such do I need?

You could always repeat the experiment - when no one was watching.
 
I thought about that, but there is usually a cop parked there.
 

Thread 'Derivation of Hamilton's Principle: Questions'

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...
