Blocks 1 and 2 of masses m1 and m2, respectively are connected by a light string, as show above. these blocks are further connected to a block of mass m by another light string that passes over a pulley of negligible mass and friction. blocks 1 and 2 move with a constant velocity v down the inclined plane, which makes an angle θ with the horizontal. the kinetic frictional force on block 1 is f and that on block 2 is 2f. 1. determine the coefficient of kinetic friction between the inclined plane and block 1 2. determine the value of the suspended mass m that allows the inclined plane and block 1. 3. the string between blocks 1 and 2 is now cut. determine the acceleration of block 1 while it is on the inclined plane.

Consider the particle-in-a-box problem in 1d. a particle with mass m is confined to move freely between two hard walls situated at x = 0 and x = l. the potential energy function is given as (a) describe the boundary conditions that must be satisfied by the wavefunctions ψ(x) (such as energy eigenfunctions). (b) solve the schr¨odinger’s equation and by using the boundary conditions of part (a) find all energy eigenfunctions, ψn(x), and the corresponding energies, en. (c) what are the allowed values of the quantum number n above? how did you decide on that? (d) what is the de broglie wavelength for the ground state? (e) sketch a plot of the lowest 3 levels’ wavefunctions (ψn(x) vs x). don’t forget to mark the positions of the walls on the graphs. (f) in a transition between the energy levels above, which transition produces the longest wavelength λ for the emitted photon? what is the corresponding wavele
