3. A particle of mass m confined to move in one dimension is in a state described by normalized wave function y (x) =vxe-*#, * >0. (1) Here is a calculation of its average kinetic energy done by a non-UVA physics student: h2 2h2x3 = w*(x) - =xp(x)m y (x)y"(x)dx = - -2dx= - (2) 2m 2m -00 2m o 2m where in the second step the fact that yo(x) is even was employed. Explain what (if anything) is wrong with this calculation, and correct it, if needed
