SUMMARY

The discussion centers on a buoyancy problem involving a block of wood floating in water. Given that the density of water is 1000 kg/m³ and that 3/4 of the block's volume is submerged, the density of the block can be calculated using the principle of buoyancy. The weight of the displaced water equals the weight of the block, leading to the conclusion that the density of the block is 750 kg/m³.

PREREQUISITES
  • Understanding of buoyancy principles
  • Knowledge of density calculations
  • Familiarity with the formula p = m/v
  • Basic algebra skills for solving equations
NEXT STEPS
  • Study Archimedes' principle in detail
  • Learn how to calculate buoyant force
  • Explore applications of buoyancy in real-world scenarios
  • Review density and volume relationships in fluid mechanics
USEFUL FOR

Students studying physics, particularly those focusing on fluid mechanics and buoyancy concepts, as well as educators looking for examples of buoyancy problems.

Homework Statement


The density of water is 1000 kg/m3. A block of wood of uniform density floats so that exactly 3/4 of its volume is underwater. What is the density of the block?


Homework Equations


b=mg
p=m/v


The Attempt at a Solution



not sure how to account for the 3/4 under water part.
