Abstract
We study experimentally the impact of solid spheres in a viscous liquid at moderate Reynolds numbers (Re ~ 5-100). We first determine the drag force by following the slowdown dynamics of projectiles. We then focus on the shape of the free surface: such impacts generate cavities, whose original shape is described and modeled.
