Find v1,f (The final speed of object 1) given the following information m1 = 5.4 kg
m2 = 9.3 kg
v1,i = 1.9 m/s
v2,i = 3.6 m/s
v2,f = 4.6 m/s

An electron is trapped at a defect in a crystal. the defect may be modeled as a one-dimensional, rigid-walled box of width 1.00 nm. (a) sketch the wavefunctions and probability densities for the n 1 and n 2 states. (b) for the n 1 state, nd the probability of nding the electron between x1 0.15 nm and x2 0.35 nm, where x 0 is the left side of the box. (c) repeat (b) for the n 2 state. (d) calculate the energies in electron volts of the n 1 and n 2 states
