hmm, I added the kinetic energy of the small mass and that only changed it a little...
Do you see any problems with my algebra? Is the formula correct?
PgM = Pgm + KM + KR + Km
Mgh = mgh + v[ srqt(.5M) + sqrt(.5I)/r + sqrt(.5m) ]
energy is conserved, no slipping or air resistance or anything.
There is a pulley, on one side is a mass resting on the ground, and on the other side is a larger mass above the ground. If the larger mass is released, what is it's speed when it hits.
okay, here is what I have:
PgM =...
Sorry to bother you guys, but can anyone explain to me how to find the standard equation of the tangent line to f(x) parallel to a given line? (so slope is known)
I desperately need to know how to do this particular thing...
Thanks!
I am doing these practice problems to study for a test and I just can't figure them out, it's kind of frustrating.
The first concerns the delta-epsilon proof.
f(x) = 2-(1/x)
x is approaching 1, and the limit is 1.
Epsilon is given at 0.1
so, what I have...
0<|x-1|<d (delta)...
I that nerd that does those extra problems in the back, the really hard ones, just for the heck of it.
Well, there is one that has me really stumped.
Show that the minimum stopping distance for an auto traveling at speed 'V' is equal to '(v^2)/(2Mg)'.
(I use M for the coefficient of...
