A particle is in the ground state of the harmonic oscillator potential V(x) = mw^2, when the potential suddenly changes to V(x) = mw^3/2. If w^2 = 5w^1, find the probability that a measurement of energy of the particle in the new potential yields a result hω^2 (write the probability in the 0 to 1 range, using 2 decimal places).
