A barge floating in
fresh water (ρ = 1000 kg/m3) is shaped
like a hollow rectangular prism with base
area A = 650 m2 and
height H = 2.0 m. When empty the bottom of the
barge is
located H0 = 0.45 m below
the surface of the water. When fully loaded with coal the bottom of
the barge is
located H1 = 1.3 m below
the surface.
ind the mass of the coal in kilograms.
How far would the barge be submerged (in meters)
if m2 = 250000 kg of coal
had been placed on the empty barge?
