Does anyone know of a calculator website or can help me find the roots of the polynomials

or a quick and efficient way of finding the roots, Im a bit confused and don't know where to start. I already know the quadratics but not polynomials

x^3-x^2-3x+3
6X^6-3x^5-7x^4-6x^3
x^5-2x^4+3x^+6x
x^5+4x^3+x^2+6x
x^4-t^3+2x^2-4x-8
x^5-x^3+x

Thanks
Narumi

a physics question?

Two 500 g blocks of wood are 2.0 m apart on a frictionless table. A 10 g bullet is fired at 400m/s toward the blocks. It passes all the way through the first block, then embeds itself in the second block. The speed of the first block immediately afterward is 6.0m/s.What is the speed of the second block after the bullet stops?

I know i use conservation of momentum but I just can't figure it out...maybe i might be plugging in numbers wrong, but could i please get some advice or help on this one?

physics/electromagnetism-help me with a few things plz?

Okay i was in a big debate with a few people over this and i did lots of reading on wikipedia and howthingswork and coudnt find everything i was looking for

-Movement of molecules-do they make a sound when they bump past one another, and if so is the sound in a measurable frequency
-Magnets-what makes them create their field, is the field putting out any kind of frequency, and if so what wave form
-AC volts-changes at 60hz but what kind of wave is it? how does it travel through the wire. is it pulsing?
and could you provide some info on the force of earth and solar system, and force of normal everyday items on eachother
