A particle in an infinite square well has the initial wave function :
Ψ(x , 0) = A [(x/L)³ - (3/2)(x/L)² + (1/2)(x/L)]
in the interval 0 < x < L and zero elsewhere.
Find (a) the wave function at a later time, (b) the probabilities of energy measurements, and (c) the expectation value of the energy.

The desk has a weight of 75 lb and a center of gravity at g. determine the initial acceleration of a desk when the man applies enough force f to overcome the static friction at a and b. also, find the vertical reactions on each of the two legs at a and at b. the coefficients of static and kinetic friction at a and b are ms = 0.5 and mk = 0.2, respectively
