Hi Nasu, I think I follow your explanation. It makes sense to me when I exaggerate the surface properties like you did (a trampoline or concrete). In regards to your questions:
1.) The parabola was a generic approximation for the sake of simplicity and also for saving the last of my brain cells...
This smells like I need to use integrals. So I looked up some more info and scratched my chin until it was a little sore. So far I'm gathering from your comment that the shock impulse should look like the following graph, (that I'm assuming too much that the acceleration is constant) and that I...
Excellent reply. I had been too focused on the time element and glossed over v² = u² + 2as. That was the missing piece - and I'm near certain I understand. However, just to be sure I understand, can I confirm the numbers in your calculation? In the examples set above, you arrive at 0.6m to be...
Thanks SophiaSimon. That thread helps shed some light on things. However, the answer to my question still eludes me. Somehow there is some time built into the explanation found on that thread hidden between the terms used: like, "rug" and "cement". I can see how a rug provides a longer distance...
Hi friendly physics gurus.
I'm trying to find equations to help answer a question I have inside my own head. I know the weight of an object (w=170g). I know the object will be subject to a shock of (1500G and time to stop t=0.5ms). My question is: what's that like in terms of how high in the...
