2. Consider the well with tunnel-barrier shown in the figure below. Assume the energy E is less than the well height V. a. Find the r and t coefficients at the second boundary x = = b. b. Find a value for energy E that is allowed in the well. Hint: Showing the parametric equations for k, plus the equations relating E and k, will be enough. Be sure to comment on the reasonableness of your answer. If you use SageMath or another algebra program, be sure to include the code. 0 a 110 b
