1. find buoyancy force, find depth
2. use Hooke's law, to find force constant
3. find frequency by using the formula for spring-mass system SHM
A 5 m by 9 m raft whose mass is 18000 kg
floats in fresh water. A 8590 kg load is
dropped on the raft. The acceleration of gravity is 9.8 m/s2. With what frequency does the raft bob up and down?
Answer in units of Hz.
