Document Summary

Not the question of optimum justice which is a question of political philosophy rather than philosophy of law. Aside a primer on necessary and sufficient conditions. X is necessary for y if it is impossible to have y w/out x. You need to be 19 to purchase alcohol in ontario. It is necessary that you are 19 in order for you to purchase alcohol in. It is necessary to write both papers to get an a in phl271. No way to get an a unless you write both of the papers. X is sufficient for y if the presence of x guarantees the presence of y. Getting an a on every assignment is sufficient for getting an a in phl271. Being a member of homo sapiens is sufficient for being an animal. Legal moralism, roughly, is the view that laws should reflect morality. W/ our distinctions in hand, we can distinguish btw several different kinds of legal.

A mass M moving in the positive x direction collides elastically with a stationary mass m. The collision is not necessarily head-on, so the masses may come off at angles. Let theta be the angle of m's resulting motion. What should theta be so that m has the largest possible speed in the y direction? Hint: Think about what the collision should look like in the CM frame.

You drag a trunk of mass (m) across a level floor using amassless rope that makes an angle theta with the horizontal (figurebelow). Given a kinetic-friction coefficient 0.65.

Determine the minimum tension necessary to move the trunk.
Tmin=______?______ mg

Determine the angle at which this minimum tension should beapplied.
theta=______?_______

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?
