Question

A wooden raft has a surface area of 5.00 m^{2} and
Volume 0.85 m^{3}. When the raft is placed in salt water
(*ρ*=1200 kg/m^{3}), the bottom 9.49 cm of the raft
is submerged. What is the density of the wood?

Answer #1

A wooden raft has a surface area of 6.00 m2 and
Volume 1.02 m3. When the raft is placed in salt water
(ρ=1020 kg/m3), the bottom 11.50 cm of the raft
is submerged. What is the density of the wood?

A raft is constructed of wood having a density of
6.00x102 kg/m3. Its surface area is 5.70
m2 and its volume is 0.80 m3. When the raft
is placed in fresh water, to what depth h is the raft submerged by
its weight? The density of fresh water is 1000
kg/m3.
Hint: Use Newton’s second to sum the forces (Buoyancy and
weight) that are in equilibrium.

A wooden raft has a density of 300 kg/m3. It has an
area of 12 m2 and is 1 m thick. Assuming that the
average mass of a person is 75 kg, how many people can this raft
hold if the raft floats in salty water with density of 1029
kg/m3?

A raft is constructed of wood having a density ρ=600
kg/ m3 Its surface area is A=5.7m² and its volume is V=0.06 m3
.When the raft is placed in fresh water of density 1 g/c m3 how
much of it is below water level?
a)0.1162m b)0.03 m c) 0.059m d) 1.89m e) None of these is true

A 290 kg wooden raft floats on a lake. When a 75 kg man stands
on the raft, it sinks 5.0 cm deeper into the water. When he steps
off, the raft vibrates for a while. What is the frequency of
vibration? What is the total energy of vibration (ignoring
damping)?

A block of wood has a mass of 3.67 kg and a density of 594 kg/m3
. Attached below the wood is a mass of lead. If the wood is to
float in water with 0.883 of its volume submerged, what mass of
lead will be needed? (Density of lead is 11.3x103 kg/m3 )

A: An airplane has an effective wing surface area of 18
m2 that is generating the lift force. In level flight
the air speed over the top of the wings is 61.5 m/s, while the air
speed beneath the wings is 58.5m/s. What is the weight of the
plane?
B: An antifreeze solution is made by mixing ethylene glycol
(ρ = 1112 kg/m3) with water. Suppose that the
specific gravity of such a solution is 1.1100. Assuming that the
total...

If your body has an average density of 989 kg/m3, what fraction
of you will be submerged when floating gently in fresh water? What
fraction of you will be submerged when floating gently in salt
water, which has a density of 1027 kg/m3?

A block of wood has a density of 700 kg/m3 . It is placed in a
fluid in which it floats with two-thirds of its volume submerged.
What is the density of the fluid? Express your answer in kilograms
per meter cubed.

A young girl (mass = 35.0 kg) is standing on a raft floating on
a pond (initial speed = 0). The raft's length is 4.00 m; it is made
of wood (density = 700 kg/m3) and has a mass of 267 kg.
The density of water is 1000 kg/m3.
a. Before
the girl gets on the raft, what fraction of its volume is below the
water?
b. The
girl and the raft were initially at rest (relative to the water),
with the...
