AI Thread Summary
To calculate the speed of a heavy device colliding with a light package, one must consider the principles of linear momentum and impulse. The light package, weighing 500 grams and moving at 250 m/min, will experience a change in momentum upon impact. The mass of the heavy device is significantly greater, which will affect the outcome of the collision. The appropriate formulas involve equating the momentum before and after the collision to find the device's speed. Understanding these concepts is crucial for accurately determining the device's required speed for the desired effect on the package.

Imagine a light (500gr) of package is moving on a conveyor from west to east with a speed 250 m/minute.

I have a heavy device(metal stick) that'll hit it from north to south direction so that the package will rotate to south keeping it's initial speed.

What should be the formula to calculate the device's speed?

I couldn't figure it out with from where to start, linear momentum formulas or impulse?

Mass of the device will be much higher compared to small packages.

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
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...
