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...
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...
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...
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 .
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...
