hi:
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?
