A bowling ball encounters a 0.760-m vertical rise on the way back to the ball rack. Ignore frictional losses and assume that the mass of the ball is distributed uniformly. The translational speed of the ball is 7.83 m/s at the bottom of the rise. Find the translational speed at the top.

OK so I understand the concept that if you have a powerful telescope you can see the light from further back in time. Theoretically, you can look back 13-14 billion years to around the Big Bang time correct? If this is correct and the space and matter which composes us and our surroundings was a product of the Big Bang, then shouldn't there be a point where it is impossible to stop seeing back in time? Sort of like you can't take a picture if you are in it? Shouldn't the light from the Big Bang a following it to a certain point have come and gone and be impossible to see?

# Where did the space for the universe come from?
# Where did matter come from?
# Where did the laws of the universe come from (gravity, inertia, etc.)?
# How did matter get so perfectly organized?
# Where did the energy come from to do all the organizing?
# When, where, why, and how did life come from non-living matter?
# When, where, why, and how did life learn to reproduce itself?
# With what did the first cell capable of sexual reproduction reproduce?
# Why would any plant or animal want to reproduce more of its kind since this would only make more mouths to feed and decrease the chances of survival? (Does the individual have a drive to surviv e, or the species? How do you explain this?)
# How can mutations (recombining of the genetic code) create any new, improved varieties? (Recombining English letters will never produce Chinese books.)

Quantum Theorys idea of parallel universes shaped like membranes bumping into each other caused the matter within our own universe.

They also feel that this doesn't happen just once but has happened several times and will continue to happen.

How do you think it will effect us if it was to happen again?

Is it possible more matter will pop up across the universe in the places they touch?

i tried it by finding dy/dx [dy/dx = 2A(x-A)] then comparision with above equation by finding (dy/dx)^2/y got the value of A and substitued the value of A but the answer does not tally. If any of you are solving by using determinants please explain. also let me know why my method is not giving me the solution

They are a "stop smoking" aid and I was wondering if anyone knew what kind of "medicine" is in it that stops cigarette cravings?
I checked the website but it was very vague on the subject of "how it works"
Thanks.

If we consider to do some repetitive stuff like typping the same keystroke, at some time we are going to fail. I think that is due to some information attached to us, which if we discovered, and altered, we are going to limit those imperfections. Doing this, will also allows us to perform better in sport, because we have some restrictions in speed, jumps, etc.Besides, have you heard that under extraordinay circumtances, we can do something (jump higher, run faster) due the the adrenaline? So please, consider this information to be useful for your answer.
