Asked by Alexis

The effective k of the diving board shown here is 1675 N/m. A heavy diver is bouncing up and down at the end of the diving board. With what frequency does he bounce up and down? How long does it take for him to complete one bounce (up and down)? What is the mass of the man?

I have no idea what to do for this… I know you're supposed to show work, but I don't even know where to start. F=1/T right?

Model it as a resonant system.

freq=1/2PI * sqrt (k/mass)

so you need the mass of the "heavy" diver.
