Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A cylindrical object with a diameter of 1 m and a height of 2 m is submerged in a lake. Calculate the buoyant force acting on it if the density of the lake water is 1025 kg/m³. (Use g = 9.81 m/s²)

💡 Hint: Calculate the volume first, then use it to find the buoyant force.

Challenge 2 Hard

Explain why a heavy steel ship floats while a small steel ball sinks, in terms of buoyancy.

💡 Hint: Consider volume displacement for both objects compared to their weights.
