Ball Fall

Classical Mechanics Level 3

A ball of density \(\rho\) is dropped from rest at a height \(H\) into a lake of water with density \(\sigma\) such that \(\sigma > \rho \). Neglecting damping forces, calculate the maximum depth to which the body sinks before turning around.

Assumptions

\(H\gg r_{\rm{ball}}\), i.e. the ball has some infinitesimal volume \(dV\).
