A 320 kg wooden raft floats on a lake in equilibrium. When a 75 kg man steps carefully onto the raft, it floats 3.5 cm deeper into the water. When he steps off, the raft oscillates for a while.

I figured out that the force constant is 21,000 Nm - first off, is that correct?

Now my QUESTION is, calculate the Frequency of oscillation (in Hz) after the man steps off the raft??????

2. Relevant equations

3. The attempt at a solution

I came up with...

2pi sqrt (m/k)

2pi sqrt (320/21,000) = .776 Hrtz
