A vehicle is traveling at 60 mph on a level two-lane road with a horizontal curvewith a radius of 1000feet. The pavement has a wet coefficient of friction of 0.30. Each lane is 12 feet wide and there is an 8foot shoulder on both sides of the road. Calculate the minimum distance that should be cleared from the edge of the shoulder if the central angle of the curve equals 35.76 degrees for the vehicle to safely stop in an emergency situation. Use the AASHTOdesign values for stopping sight distance.

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
