my questions says the following:

A tuning fork labeled 392 Hz has the tip of each of its two prongs vibrating with an amplitude of 0.600 mm.

What is the maximum speed of the tip of a prong?

for this part i found omega= frequency*2pi

then plugged that in V= omega*Amplitude, so my answer is 1.48 m/s.

Now in the second part of the problem they ask:

A housefly with mass 0.0270 g is holding on to the tip of one of the prongs. As the prong vibrates, what is the fly's maximum kinetic energy? Assume that the fly's mass has a negligible effect on the frequency of oscillation.

is this the formula i have to use ?--> E=.5mv^2 + .5 kx^2, if it is, please how can i find x ? do i get k from omega = sqrt(k/m). i'm not sure what to do for this part. which equation should i use?
