Challenge Problems
Push your limits with advanced challenges
A basketball of radius 12 cm falls through a substance with a viscosity of 10 kg/(m.s). Calculate its terminal velocity, given that the density of the basketball is 0.6 kg/m³ and the density of the substance is 1.2 kg/m³.
💡 Hint: Substitute the values correctly and pay attention to unit conversions.
A sphere falls through a viscous liquid at a velocity of 2 m/s. If the density of the sphere is 3000 kg/m³ and the density of the liquid is 1000 kg/m³, calculate how changing the radius of the sphere to half affects the terminal velocity.
💡 Hint: Focus on how radius affects the outcome in the terminal velocity formula.
