ok, i see, but the example in the book has the initial wavefunction given as Y(x,0)=Cexp(-|x|/x0) where C and x0 are constants, is it possible to get this function into a similar format??
Homework Statement
Consider a particle in a superposition of states given at time t=0 by Y(x,0)=C(y1(x)+y2(x)), where y1(x) and y2(x) are the stationary states with energies E1 and E2 respectively. if y1(x) and y2(x) are orthonormalized, what value of C is required to normalize Y(x,0)...
ok thanks, i think I have bridged the gap in my knowledge, one more quick question though...in Acos(kx)+iAsin(kx) the i doesn't play a role does it? I mean its just like a negative sign??
ok, that makes some sense, so since the position operator [x] is just x, then all of the functions are eigenfunctions...similarly, the potential energy operator [U] is just the potential energy function. In this case the function is zero so since its [U]=0 all the functions are eigen functions...
Homework Statement
given the following functions:
y(x)= Acos(kx)
y(x)=A sin(kx)-Acos(kx)
y(x)=Acos(kx)+iAsin(kx)
y(x)=A d(x-x0)
Which are eigenfunctions of the position, momentum, potential energy,kinetic energy, hamiltonian, and total energy operators
Homework Equations
y(x) is...

Homework Statement
an object of .4kg is attached to a spring with given spring constant 400 N/m. it is moving on a tilted table, that is at 30 deg from teh horizontal. The table is frictionless, but there is a dampening force -bv proportional to velocity. when the object is driven, the...
ok i see where your comin from the derivative of the vector with respect to time is the vector with the derivatives of the components with respect to time
Is this a simple harmonic question or no??
Homework Statement
a particle moves on the x axis under the influence of a force, proportional to its distance from the origin, attracting it toward the origin. The particle starts from rest @x=10cm and reaches x=5cm in 2 seconds for the first time...
so your tellin me that these functions are vectors? Ok i can dig it, so i take the derivative with respect to time and i'll have the velocity, take it again and i'll have the acceleration. That seems to be too simple, but i'll try it
ok but i'm not seein it? the block is on a ramp, so with the incline mg is straight down while the normal force is perpendicular to the surface of the ramp at angle theta. So i don't quite see how to solve for the velocity...

No, i understand the normal force is Fn(normal force) cos(theta). And as for the equations thats just my understanding of the forces on the block, the one set equal to (ma) is the equation for motion of my system as i believe...
