Well I don't know if I can help you for the test but it sounds like your on the right track, enjoying physics is the key to learning it. When I first started as a physics major it took me a while to get the concepts - what I did was over the weekend I would finish all my homework then read the...
I think you are on the right track. With problems like these the first step is to draw a free body diagram then sum the forces - perhaps the problem states that the rocket is taking off from Earth? After summing the forces you should have the answer for the Total a. Let me know if that helps...
I'll take a crack at the first problem...I’ve got a bit of a cold, but I think your right. The first question is a proportionality question. If you know that T1=754N and F1=261.6Hz then perhaps an equality would solve this one, you already know what F2 is, now all you need is to solve for T1...
I'm a peer leader for a general physics lab and someone asked me to explain what the Dot Product meant conceptually.
I told him it was the projection of A onto B multiplied by the magnitude of B.
He looked even more confused after that; my questions are:
a) Did I explain it correctly...
I think Acceleration might be the easier one to answer so I'll start with that. The truth is both! Humans can experience acceleration (pilots can black out from "experiencing" 4+ Gs). If I have acceleration and so do you I may measure your acceleration to be relative to mine; you may...
