A 340-kg wooden raft floats on a lake. When a 80-kg man stands on the raft, it sinks 3.2 cm deeper into the water. When he steps off, the raft oscillates for a while. Part A What is the frequency of oscillation? Express your answer using two significant figures. f= ___________ Hz Part B What is the total energy of oscillation (ignoring damping)? Express your answer using two significant figures. Etotal = _____________ J

A young boy at summer camp stands on a wooden raft (ρw = 700 kg/m3 ) floating in a freshwater lake (ρ = 1000 kg/m3 ) and finds that his weight just cancels the buoyancy of the raft; the water touches the soles of his feet but the raft doesn’t sink. He then jumps onto rectangular block of Styrofoam (ρs = 50 kg/m3 ). The Styrofoam has 1/3 the volume of the wooden raft, but now the top of the...
