Brian needs to protect a science station from a shock wave. Apply the correct equation to determine the energy of the shockwave, if it has a frequency of 8.00 x 10^6 Hz and an amplitude of 3 meters. The mass of the particles is 0.15 kg.

hmm... I'm not sure if I understand the problem right

you are looking for the energy, which is given by the equation 1/2mv^2 (based from the explanation given)

you are also given f= 8 x 10^6 Hz or /s
amplitude=3m
mass=0.15 kg

let me brainstorm a lil bit
speed of a wave is given as: v= wavelength x frequency
but I don't think that will help because we don't know the wavelength..hmm

UNLESS, we use the relationship between E and A, which is given as: E=1/2kA^2 (derived when Ek=0)

hmm.. give me a sec to figure this one out @_@
