Problem 14.78

A 320-kg wooden raft floats on a lake. When a 75-kg manstands on the raft, it sinks 3.5 cm deeper into the water.When he steps off, the raft oscillates for a while, (a) What isthe frequency of oscillation? (b) What is the total energy ofoscillation (ignoring damping)?

Step-by-Step Solution:
