Consider a free particle moving in one dimension (a) write down the stationary schrödinger equation for the particle. (b) bearing in mind that the particle's energy must be positive, verify that the solution of the stationary schrödinger equation is of the form 6(x) = a sin(kx) + b cos(kx) and determine k in terms of eand m. (c) verify by substitution into the stationary schrödinger equation that (1) = cei + deika is also a solution, with the same k. determine c and d in terms of a and b.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.

no

explanation:

no i dont know how to solve this you should probably try to google the answer
