Answer to Question #256554 in Classical Mechanics for Lemoj

Question

An aluminum ball of mass 54.0 g and density 2.70 g/cm³ is placed in a beaker filled with water. a.) What is the volume of the ball? b.) What is the volume of water that will spill out of the beaker? c.) What is the buoyant force of the water on the ball?

Answer 1

$$V=\frac{54}{2.7}=20\ cm^3\\V_w=V=20\ cm^3\\F=(1000)(9.8)(20)10^{-6}=0.20\ N$$
