If the US went to 80% nuclear fission energy how log would it last? I understand that we can have breeder reactors that extend the life of nuclear fuel by converting it to plutonium, but would we run out of fissionable material in 100 years? 1000? Can we make it last until we come up with a fusion reactor?

lightning bolt = 100,000 mph = 1666.6666666666666666666666666667 miles per. sec.
one mile = 5280 feet = 105,599,999.99999999999999999999997 inchs

ok so how long would it take it to travel one inch?

point A to point B is 2 inchs. What would the frequency be if it could be sustained?

I've been reading much on string theory lately and am familiar with physics as I have a minor in it from college. It seems as though everytime the particle physicists think they have it, problems arise one by one and they have to expand or change the theory. Now many are calling string theory "the theory formerly known as string theory". And now 5 dimensional models are coming up and so on.
So I'm having my doubts if they'll ever arrive at a fundamental set of rules that governs everything and has no problems with it(certain experimental observations that just don't fit into the model). It seems as though the best we can do is conceptualize and model in our heads and who knows if these things are reality or just agree very well with our experiences and experiments.
In light of this, do you think it's possible, to get to a point where we clap the dust off our hands and say, "That's it, nothing really more to learn. Just details at this point."?

A crate of mass m1 on a frictionless inclined plane is attached to another crate of mass m2 by a massless rope. The rope passes over an ideal pulley so the mass m2 is suspended in air. The plane is inclined at an angle = 36.9°. Use conservation of energy to find how fast crate m2 is moving after m1 has traveled a distance of 1.4 m along the incline, starting from rest. The mass of m1 is 10.4 kg and the mass of m2 is 12.5 kg.

the derivative of distance is velocity, but does the integral of distance have any physical meaning at all?

My guess is that it would have the units of distance*time, is this right and are there any physical measures with the units distance*time?

A 207-kg log is pulled up a ramp by means of a rope that is parallel to the surface of the ramp. The ramp is inclined at 31o with respect to the horizontal. The coefficient of kinetic friction between the log and the ramp is 0.87, and the log has an acceleration of 0.87 m/s^2 . Find the tension in the rope.
