dv/dx*v=dv/dx*dx/dt = dv/dt = a

A particle of mass m is subject to a force F(v) = bv^2. The initial position is zero, and the initial speed is vi find x(t) so far m*dv/dx*v = -bv^2 m*dv/dx = -bv integral m/-bv*dv = integral dx m/-b*ln(v) + a = x + b What do I do with the constants? i thought i was suppose to put...

i thought symbols had one meaning attached to it though. Don't people decide what concept the symbol is going to represent? For instance the bathroom door sign? the one without the skirt is men?

i don't get it if whatever is moved is moved by something else, and if momentum is conserved, then how is it that we have any free will? I am typing this, but if my hands are moving because it is moved by something else, then what's the point? what's the point of everything? why are we...
