Problem Sketch Okay so this is the problem the upper disk will be of M1 mass and R1 radius both disk are solid so I(oe)=1/2MR^2 , the second disk will be HM2 , HR2. After system is left from rest I understand that the lower disc will start rotating and going down from the rope also it has...

The problem is: we have a rope of total mass M and length L the rope starts from rest on surface and being pulled up by a force F , it's pulled up with constant speed V until the upper end reaches height x . Find the power (P) needed the pull the rope up as a function of X . What I did...

I got it's the same : I can integrate f(t)v(t)and then def. by dt so its = power or just skip it and f(t)v(t) is my power ! thanks a lot ...

yes but you don't put in consideration that x is function of t it\s integral of F(t)d(x(t)) or something 2) I know that p=FV when the force is constant here it isn't ?!

I have a question where I have a force F(t) acting on particle , I intgrate 2 times and find X(t) , i used innitial conditions given x=0 , t=0 , v=0 . 1) now they ask me to write the work done by the power between t=0 , t=<epsilon> I know that dw=F dot DX but here the f and x are both...

okay got it I get 2nd order eq. thanks a lot

Hello all , I encouter a problem solving this one : We are given a conical pendulum with : V - tan. speed of particle m - mass of rotating particle g - gravity acceleration...

Thank you very much I got it , good to know there are wise people out there.

I can post the answer for you it goes like : v=(3xp/m)^(1/3)! The question is from Resnick Physics 1 4th edition chapter 7 problem 52 , I suppose the answer is correct .

Already made but the answer is given by x ,p ,m and factoring numbers ! I think DX/DT is needed ??/

No I'm not so good with diff. equations .!

Hello all I encounter a difficulty solving most simple problem related to constant power and speed of particle the problem is as follows: Express the speed (V) of a car given a constant power P , the mass of the car is m, the car travels distance x and it at first was at rest. I...
