Spin beams are mixed in an experiment, |+)z _and |+)x with probabilities p = 1/3 and p = 2/3, respectively, are mixed. these beams pass through a stern Gerlach machine with magnetic field B with þolar angle 0 and azimuthal angle o = 0. Then, а. Write p(0) b. Find the probability of measuring +ħ/2 and –ħ/2 ħgSx с. If before entering the Stern Gerlach evolves with H = for a time t, calculate p(t) and (Sx).

Problem 4: Speed deamplifier. In the figure above on the right, block 1 of mass m1 slides along an x-axis on a frictionless floor at speed 4 m/sec.Then it undergoes a one-dimensional elastic collision with stationary block 2 of mass m2 = 2m1. Next, block 2 undergoes a one-dimensional elastic collision with stationary block 3 of mass mz = 4m1. What then is the speed of block 3? Answer: 16 m/sec or 1.78 m/sec.
