Question

A 165 kg boat is sinking in the ocean. The

boat's weight is partially offset by the 790 N
buoyant force of the water. What is the net
acceleration of the boat?

Answer 1

F:: buoyancy force (N)

p: density of fluid (kg/m")

V: volume submerged (m3)

g: acceleration due to gravity (m/s?)

F: weight of boat

Buoyancy is the upward force on

an object submerged in a fluid

Objects submerged in a fluid experience a force

that pushes them towards the surface. The

buoyant force is directly proportional to the

density of the fluid, p, the volume of the fluid

displaced, V, and the acceleration due to

gravity, g:

Fb=p• V. g
