When a mass undergoing longitudinal vibrations experiences an
externally applied force, it is said to execute forced vibrations. The
applied force is generally taken to be a sinusoidal function of time [F=Fsinwt]. Choose any other time function for this force and
derive an expression for the amplitude of resulting vibrations. Force
constant of the harmonic oscillator is k and the mass undergoing
vibrations is m
