Homework Statement
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?
Homework Equations
The Attempt at a Solution
I came up with...
2pi sqrt (m/k)
2pi sqrt (320/21,000) = .776 Hrtz
