A vibrating structural beam in a spacecraft can cause problems if the frequency of vibration is fairly high. Even if the amplitude of vibration is only a fraction of a millimeter, the acceleration of the beam can be several times greater than the acceleration due to gravity.

As an example, find the maximum acceleration of a beam that vibrates with an amplitude of 0.30 mm at the rate of 130 vibrations per second.

a max= ____ m/s^2
Also, give your answer as a multiple of g.
