The non-Markovian Fokker-Planck equation in the energy variable for a system with a driving force is employed to find the escape rate of a particle in a potential well. The energy-dependent diffusion coefficient is the integral of the spectral densities of the applied force and the velocity of the system. The escape-rate formula is applied to resonant activation of a Josephson junction by a microwave driving current with a good comparison to experimental results.
