Document Summary

The problem of personal identity: comprised of several questions about: Sameness: qualitative identity: two things that look the same, numerical identity: one thing that is actually one and the same. Body theory (animalism: we are identical to our biological bodies throughout time. Strengths: we exist as long as our living bodies do. The nonphysical soul is unchanging, so personal identity is not affected by the death of our bodies. Quasi-memory: an experience: that we seem to remember, that somebody actually had, that is caused by an actual experience. Personal identity is defined by psychological connections between different life stages. Problems for memory theory: memories are inconsistent or fade, false memories. Quasi-memory: an experience: that we seem to remember, that somebody actually had, that is caused by an actual experience, repudiation. Can be recalled consciously at this moment: indirect. A former self was able to recall them.

Particles of mud are thrown from the rim of a rolling wheel. Ifthe forward speed of the wheel is v₀,and the radius of the wheel is b, show that the greatest heightabove teh ground that the mud can go is

b+(vo^2)/(2g)+(gb^2)/(2vo^2)

at what point on the rolling wheel does this mud leave?

(note: It is necessary to assume that vo^2 â¥ bg.)

----------------------------------

This is a question from the book "Analytical Mechanics" seventhedition by fowles and cassiday. chapter 4 problem 7. cramster "has"the solution worked out but two problems. 1) it's wrong and 2) itis damn near impossible for me to follow.

The person doing the problem just pulls random equations out touse without saying why. If i knew why they were being used thatwould basically solve most of my problems about the question. Alsothe few discriptions the problem has seems to have very badgrammar/punctuation and so trying to follow it is nearimpossible.

So any work through of the problem would be great. But more ofwhat I'm looking for is what should be going through one's mindwhen proceeding with the problem? What equations should be used andWHY?

Concerning problem 19 of chapter 18 in the physics 8th edition by Cutnell, Johnson, there is an error that should be corrected. The question asks for the magnitude of "acceleration" which is in m/s^2. The answer from the actual book gives a very different answer than Cramsters.com indicates although both questions are identical. There is obviously a discrepancy. Thank you, Robert.

I had previously worked this problem but after trying toformulate the Lagrange for r and phi, my work became a jumbled messthat took several lines of paper to write down. I thought this wasa problem so I checked Cramster to make sure I was following thecorrect path and found that the Cramster formula for Kinetic Energywas much different from mine. I found the correct answer forPotential Energy, but I do not understand how the Kinetic answerwas formed. The way I originally started the problem was by makinga drawing which was exactly like the one in the answer key andwriting out the conversions from Cartesian to sphericalcoordinates.

x = rsin(Î±)cos(Ï)

y = rsin(Î±)sin(Ï)

z = rcos(Î±)

The kinetic energy is then

T = (1/2)m[d/dt((rsin(Î±)cos(Ï))^2 + (rsin(Î±)sin(Ï))^2 +(rcos(Î±))^2)]

Applying the time derivative makes a mess of things and trigidentities are not simplifying things which has led me to theconclusion that something must be wrong in my initial setup. What Ido not understand is how the Cramster answer has a kinetic energyof

T = (1/2)m[rdot^2 + (rsinÎ±Ïdot)^2]

If an explanation of how this is achieved can be provided, Iwould be incredibly grateful.
