I'm having trouble understanding how to find out whether or not a stationary point is a minimum and I'm hoping for some clarification. In my class, we were shown that, using Euler's equation, the straight-line path: with constants a and b results in a stationary point of the integral: A...

The passengers wouldn't be accelerating since the car is at a constant speed which, of course, means there's no net force.

This is just a general question based from a personal conversation I had.

What would the forces acting only on a passenger in a car going at constant speed on a level surface be? Of course, there would be weight and the reactive force acting on any passenger, but is there a horizontal net force? Or are there just the forces acting on the car and there are no...

I have a graph of mean signal (per pixel) vs exposure time (sec) for 8 different dark frames. I am being asked to find the bias in ADUs/pixel and the dark current in ADUs/sec/pixel and I am very confused on how I could get it. I know that the average of all of the mean signals is a rough guide...
