A tuning fork labelled 392 Hz has the tip of each of its two prongs vibrating by amplitude of 0.600mm
a) What is the maximum speed of the tip of a prong?
b) 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? Suppose that the fly's mass has a negligible effect on the frequency of oscillation?
